A delay in one gross motor milestone is generally not a cause for great concern. You must take into account that your baby is an individual and will progress in life at his own pace. However, if your baby shows a cluster of delays you may want to bring it up with your pediatrician or go and see a pediatric physiotherapist:
- Did not roll and does not crawl by 11 months
- Is not sitting by 8 months and is not engaged with his world
- Smiled late and never rolled and is not sitting
- Dislikes movement and going in the car and has not rolled or sat
- Not walking by 16 months
- Sat after 6 months, never crawled and is not walking at 14 months
- Very happy to lie on his back at 8 months and sat late
