I've used all of what @nelianiz.elize @unbecomingme @abbyrose16 because Lucas just gets super comfortable.. But the thing that helps the most is a baby in just a diaper. And finding any ticklish spots(feet, finger down the spine, ears) Just be careful not to caress instead of waking up. I'll pat his butt to get him to suck when he's just laying there too.. My secret weapon for when it all fails is to take him off and trying to burp him . Even if he gets upset I to for a couple minutes or he just falls back asleep.

I don't breastfeed up I heard taken there clothes off and wake them up

Tickle her feet. (more like scratching...) but now that's she's a little older I just remove her. Lol

Remove it once she falls asleep and make sure she is actually crying when asking for it ...
