What could it be?

Chloe • One little baby girl! 🌸

Has anyone else noticed their little one either sucking in their top or bottom lip. It looks like she’s chewing it when she does it but I don’t know if it could be a sign of teething or something she’s just found out she can do. Granted though it is hilarious when she does it because she looks like a little old man with no teeth 😂
