Development milestones 1 to 6 months

Baby Developmental Milestones

1 to 6 months

This is a guideline for baby developmental milestones during the first year.

It’s so exciting the first time they smile at you and then at each other. So when do babies generally start to smile and grasp, crawl and start teething? This is a guideline only of when a baby may accomplish each milestone by month. Not necessarily in this order exactly or exact age especially if they have an adjusted age
