He actually started in it a little less than 2 months...BUT at the point the back was high enough for him to lean his head on. Once he got a little taller we had to take a break from it because he wasn't able to hold his head up very well. His head would fall back after a few minutes if we put him in it. After a few weeks he was able to sit in it again. He can sit in it just fine now.
I heard it's supposed to be 3 mo, so we tried then. Sadly, my chunky monkey has such chubby thighs, and she is so big in general, that she stopped fitting in it after a few weeks- too funny!
Re: when was your LO able to sit in the Bumbo?
