It is important to understand that twins may not reach their twin baby milestones exactly as per the above development milestones, and that is also fine as there are a number of factors at play, but generally full term twins meet the milestones as above.

If you are at all concerned about the development of your children, or if you think your baby is considerably lagging behind in one or more developmental stages, then speak to your pediatrician and recommendations will be made from there.
