My baby is 16 days old, he is dc 2. I ebf his sister with no problems to 9 months, naively thought it would be plain sailing this time too 
He can feed for up to an hour, fall asleep at the breast and wake 5 mins later rooting for more milk. He doesn't seem to latch on properly 80% of the time, just sucking on nipple...
At 6 days I caved in and sent dp out for some formula, he guzzled about 4oz. He is now needing 3 4-5 oz bottles of formula as well as pretty much constant bf day and night... A friend suggested he may be tongue tied, I mentioned it to midwife today and she's referred us to a bf/tongue tie specialist with a view to snipping if necessary.
Has anyone else had this? What was the outcome? Could you go back to ebf? If its not tongue tie, what can I do? TIA
