Parents have been sharing #milkdrunkbaby photos showing their babies half asleep and smugly satisfied with a belly full of milk.
The trend was started to tie in with World Breastfeeding Week, but as we all know, it's not only breastfed babies who have those brilliant milk drunk faces.
Here's a few satisfied babies enjoying the aftermath of their feed.
