Bottle teat size help!

[babyno2dust]

Hi,

My LO is 12 weeks old and is formula fed.
She is currently on the size 2 teats and has been for a couple of weeks, and was feeding fine up until now.
This last few days when feeding a lot is dribbling out of both sides of her mouth to the point the bib under her chin is soaked!

Is this a sign that the teat is too big and I need to go back down a teat size?

Just confused as to why it's only just started happening.

Thanks!

Sorry @babyno2dust I don't know the answer to that one. Hopefully some will be along soon.
