The first time our first son started crawling, I was trying on shoes at a shop, and he establish my ratty, discarded sneakers besides enticing to ignore. He went for those shoes like a lion afterwards a gazelle, right on schedule — between six and 9 months old. Our second son, however, baffled (and amused) us when he began scooting instead of crawling. Our first was boilerplate-sized, but our second was extra chubby, and so scooting on his buttocks seemed easier for him. He scooted effectually the business firm faster than his brother had ever crawled, simply we didn't know whether to exist impressed with his speedy efficiency or worry that he never got on all fours. His pediatrician didn't seem concerned. One day he just got upward and walked.

"While nearly typical kids crawl, non all do," said Dr. Gary Noritz, M.D., an associate professor of pediatrics at Ohio State Academy, director of the Comprehensive Cerebral Palsy Program at Nationwide Children's Hospital and lead author of the American Academy of Pediatrics' clinical report on motor delays.

Rolling and itch both tend to be softer milestones that are less essential to subsequent developmental stages than sitting and walking, Dr, Noritz said.

Historically, babies were expected to be able to roll in both directions — front to back and dorsum to front — around 4 to 5 months. (Dr. Nortiz estimates near 85 to 90 percentage whorl past half-dozen months, based on an early gross motor study and the Denver Developmental test, though there's footling solid information on the subject field.) Expectations changed after the Back to Sleep campaign began in the 1990s. It told parents to put their children to slumber on their backs to reduce sudden babe death syndrome (SIDS), explained Dr. Lisa Asta, One thousand.D., a clinical professor of pediatrics at Academy of California San Francisco School of Medicine. The campaign worked — SIDS rates dropped past half — just babies now spend much less time on their stomachs, a placement that encourages musculus evolution when they try to push button upwards and roll over.

"Sometimes there isn't a problem with the child. It'south more of a problem with what kind of life experiences they've had," Dr. Asta said. "Information technology'south important for parents to requite the babe the surroundings, and positioning for these developmental milestones will come."

It's easier for babies to roll from their stomachs to their backs first, Dr. Asta said, and doing that merely once is oftentimes all the motivation a baby needs. "Frequently that commencement roll is completely accidental, and so babies realize, 'Wow, look at this whole globe now that I've rolled dorsum,' and then they'll repeat that activity," Dr. Asta said. "But if you're non put on your belly, you're not going to have that experience."

The recommended tummy time is at least 30 to 60 minutes of awake fourth dimension over a 24-hour menstruum, said Dr. Jennifer Shu, K.D., author of "Heading Home With Your Newborn" and a pediatrician based in Atlanta. "Tummy time can strengthen the muscles they're not using while they're lying on their back and gainsay flat heads."

Parents tin likewise entice their children to roll over or clamber by putting toys just out of reach. "It depends on the personality of the child," Dr. Asta said. "Some of them are like Indiana Jones and some kids are more cautious."

When it comes to supporting your child's development, all you need is a towel or blanket to set your kid on and any toys or interesting objects you tin can use to encourage them to brand a move. Some items, such equally Bumbo seats or Boppies, give parents an opportunity to melt dinner or exercise other household tasks while the child remains in one place, but these are conveniences for parents, not tools that aid development, Dr. Shu said.

If your child is exhibiting awkward or unusual movements, they may non demonstrate them during a well visit. So Dr. Shu recommends that parents attempt to video the movements. (This is what nosotros did when our younger son made foreign facial movements that looked like mini-seizures, which were ultimately determined to be reflux after testing revealed no neurological abnormalities.)

Pediatricians should have two actions when a child appears to have delays or atypical muscle tone: send the child to concrete or occupational therapy and refer the kid to a specialist who can exercise a diagnostic workup looking for potential disorders.

Worried about the cost of therapy? You lot might not accept to, as many early intervention services are complimentary in every state, regardless of parents' income. Other services may come with a fee, but it'south charged on a sliding calibration, and no kid can exist denied services they need merely because a parent cannot afford to pay.

"Sending them to therapy early is important because the encephalon is plastic the more you starting time working with a kid," Dr. Noritz said. "There are lots of kids who will exist a fiddling behind in these milestones or peradventure a trivial bit floppy, and near of these kids don't have a motor disorder," Dr. Noritz said. "They may be behind, simply they'll take hold of up."

Other, more serious and rarer weather condition may have new or emerging treatments — for instance, a new drug was recently canonical for spinal muscular atrophy. "That's why nosotros have to have an early diagnosis, so they can get to the right places or get into a clinical trial," Dr. Noritz said.

The therapy a child receives will depend on their needs. For example, for children with bilateral cerebral palsy — where only one half of the body is affected — constraint therapy is constructive, particularly the before it's done. "If they have a good or bad side, you lot constrain the practiced side and forcefulness them to use the bad side, and information technology rewires the encephalon," Dr. Noritz said.

Parents whose children don't curlicue over by 6 months or clamber by 12 months should lookout man for other delays — for example, not having head control by 2 to iv months, non sitting independently past nine months or non walking by xviii months.

They should permit the doctor know well-nigh unusual muscle tone, such equally babies who experience particularly "tight" or "floppy," Dr. Noritz said. "Ane of the hallmarks of floppiness is if yous experience like yous accept to concord onto the kid actually tight or else they're going to drop through your hands," he said. Floppiness can indicate peripheral nervous system problems, such as muscular dystrophy, and tightness may be a sign of cerebral palsy or a central nervous arrangement disorder.

"If the baby is super stiff and doesn't relax when y'all're holding them, that can exist sign of a trouble," said Dr. Shu. "Stiffness or beingness too rigid can sometimes come across as being too strong, and being really, really strong is not necessarily a good thing if it just means the baby is too rigid and inflexible."

Parents should also watch for twitching, jerking or writhing and serpent-like movements — a child who seems to lack command over their limbs even when trying to stay notwithstanding, Dr. Shu said. Movements that await nonpurposeful, off-kilter or asymmetrical are also worth mentioning to your kid's doctor.
