Early Signs of Gross Motor Delay in Children
Gross motor delay means movement milestones — head control, sitting, crawling, standing, walking — arrive noticeably later than expected. The milestones are the same for boys and girls. Watch for not sitting by 9 months, not walking by 18 months, persistent floppiness or stiffness, or any loss of a skill. These are reasons for a friendly check, not a diagnosis.

Every little one finds their feet on their own timeline — but some patterns are worth a gentle, closer look, and noticing early is a gift, not a worry.
In short
Gross motor delay means a child reaches movement milestones — holding the head up, sitting, crawling, standing, walking — noticeably later than expected for their age. There is no separate set of signs for boys; the milestones are the same, though every child's pace varies. Early signs are simply a reason for a friendly developmental check, not a diagnosis — and most are picked up and supported beautifully when noticed early.
Early signs to gently watch for
These are patterns that persist over time, not a single missed week:
Babies (around 3–9 months)
- Floppy or unusually stiff body when held; head still flops back at 4 months
- Not pushing up on arms during tummy time
- Not rolling over by around 6 months
- Not sitting with support by 6 months, or without support by 9 months
Older babies & toddlers (9–18 months)
- Not crawling, bottom-shuffling or moving across the floor by around 12 months
- Not pulling to stand by 12 months
- Not standing with support, or taking steps holding furniture, by around 15 months
- Not walking independently by 18 months
At any age, worth a same-week check
- Losing a skill the child once had (rolling, sitting, standing)
- Strong, persistent preference for one hand or one side of the body before 18 months
- Markedly stiff, tight or very floppy limbs
When to seek a check
"Wait and see" is fine for a child who is steadily progressing, even a little behind. Seek a developmental check when a milestone is several months late, when progress seems to stall, or — most importantly — if your instinct says something feels off. Parent concern is one of the most reliable early signals. Any loss of a skill warrants prompt medical review rather than waiting.

CONNECT THE ANSWER TO YOUR CHILD’S DAY
Something to notice. Something to discuss.
What to notice
Seek a prompt medical check if your child loses a skill they once had, shows a strong one-sided preference before 18 months, or has markedly stiff or very floppy limbs — these warrant review rather than waiting.
In everyday life
Give plenty of supervised floor and tummy time each day — reaching, rolling and pushing up on the floor are how babies build the strength for sitting, crawling and walking.

Bring your questions to a first visitQuestions families ask
Are the signs of gross motor delay different in boys?
No — the movement milestones are the same for boys and girls. While children vary in pace, the milestones we watch (sitting, crawling, standing, walking) and the ages they're expected by are not different by sex. The same gentle checks apply to every child.
My baby skipped crawling and went straight to standing — is that a delay?
Not necessarily. Some children bottom-shuffle or pull straight to standing and skip crawling entirely, and still walk on time. What matters is steady forward progress in mobility. If your child isn't moving themselves across the floor by any method by around 12 months, it's worth a check.
When should I worry about late walking?
Most children walk independently between 12 and 15 months, but anywhere up to 18 months can be typical. If your child isn't walking by 18 months, or isn't pulling to stand by 12 months, book a developmental check. Any loss of a skill needs prompt medical review.
