Lifting your baby after a c-section should be perfectly fine, but you should take it easy and if you do feel any pain or discomfort then you should lay your baby back down immediately. You must avoid lifting anything heavier than your baby for the first few weeks after your c-section, as this will put unnecessary strain on your weakened stomach muscles.
If heavy lifting is not avoided after a c-section it can lead to complications such as bleeding, infection and a longer recovery time.
