Bad sleep habits

Amber • Mommy to an amazing little boy!💙 Baby boy #2 July 21💙

For the last couple of weeks, maybe even closer to a month, my son has been sleeping horribly. Waking up every 1-2 hours just wanting to snuggle. We’ve resorted to putting him in our bed, or sleeping on the couch with him. How do I break him if this habit before it get worse? He has a zen sleep sack that doesn’t do anything for him at all...we’re so exhausted! Thanks ladies!
