Just after some guidance please.

My little girl is 5 weeks old. We have experienced trouble with her latching to the breast. At 2 weeks she had her tongue tie cut yet since this time her feeding has not improved. Thankfully I am able to express and offer this in a bottle which she takes without issue.

My concern is she usually has around 400 (14oz) of breast milk. Is this to little for her age?

There’s no issue with my supply as I’m able to express regularly and if I don’t I tend to find my breasts become sore, but she doesn’t seem to want more milk and feeds around 12 times a day.
