She’s just eager to try! My son does this too when he is excited to eat and he is in 96% percentile so big boy. I wouldn’t worry. Nothing to do with her size x
As long as she’s up right and not slumping (which she looks like she’s doing the opposite) she’ll be all fine. She looks like she’s loving life and weaning!!!! She’s an absolute cutie
Looks like she’s just leaning forward eager to try the yummy food to me xx
