Only sleeps with nipple in mouth

Kylie

Little dude will only sleep with a nipple in his mouth. No matter whether it’s nap or bed time he immediately wakes up once it’s out. I can’t get him to take a paci so I am just holding him on my boob almost 24/7. It doesn’t matter if I take it out or if he falls asleep and it slips out. Please give me any suggestions I’m really struggling with this. He has fallen asleep in his car seat a few times but wakes quickly once the car stops moving. Considering trying taking Cara babies course but also scared my supply will decrease if he’s not at the breast as much.....
