Mine does that too. One week he never stops eating and the next he's not even eating his meals. His weight has been hovering between 29.5-31 lbs for a few months now.

He's adorable :)

My lo is only 26 lbs and goes through phases where she will eat non stop and then barely anything for a while.

Mine won't eat OR sleep through the night! But he's still frickin' awesome ;)

Wow! My son is only 25 lbs! Can't get him to eat!! Lol
