Can babies get fat? 🤔

My baby is five months old and my mom keeps telling me I need to not feed her so much. I told her the doctors say she is perfectly healthy, just big. Can babies this young actually get too big? I just feed her when she is hungry..

UPDATE: Thank you all so much for the replies! I feel a lot better! Lol. And thank you for all the compliments, I am pretty proud ❤️😍

Here are some more photos since everyone enjoyed them so much ❣️
