Been breastfeeding my LO (13 days old) had some issues with latch and tongue tie but hopefully sorted now. Anyways today after I've been feeding him he now has something on his lip that looks a bi5 like a blister, doesn't seem to be bothering him but just wondered if this is normal? Also does it tell anything about the latch? Just seems to have appeared after he's had his tongue tie done and since I've had a lactation consultant out so don't know if it says he might not be latching properly or if it's just coincidence? TIA
