Can’t get baby to go to sleep...

Cara

The only way I can get my one month old to sleep is to put her in a body carrier, then after about 30-45 mins I can lay her down because she’s fallen asleep. I don’t want to rely on this to put her to sleep for every nap and bed time but I dont know what else to do to get her to sleep 😩 I can rock her for what seems like forever just to have her wake up 10 minutes later.
