Definitely signs of good milk intake - lots of wet nappies, and he's putting weight on. I've had him checked for a tongue tie. Sometimes he does fall asleep on the boob so swapping sides more often might help HotI. But currently he has each side once, alternating which one I start with. I think I'm a bit scared of dropping the shield as the start of our BF journey was so painful for me (scabbed bleeding nipples) that I don't want to end up back there. But maybe I should try some day feeds without the shield and see how he goes. It is easier just to chuck the shield on though!
