Hello moms... my baby is 7 months old... she is trying to sit up and crawl since past 15 to 20 days but is unable to do so yet.. is it a matter of worry???

A. A child also said by the age of eight months to 8 1/2 months and the crawling comes in the picture of 9 to 11 months so if your child has started doing it it is a positive sign but the child will take time to reach the milestone
