I keep telling my 3yo that’s it’s much funner being a big girl. That means she can eat all her fave things (like ice cream) and play with her friends. I’ve been reading a book which says similar things and it does seem to be helping. She still has her baby moments but as you say it’s normal x
My little girl who is 3 & a half has been doing similar things. Saying I just want to be a baby again. I’m just going with it for now and just talking her through that it’s really exciting being a bug girl because she can do x,y,z and show baby how to do all these things too xxx
