Because after a year and 5 months of co sleeping I'm trying to get my son to sleep in his crib that he's never slept in and I hide in our bathroom until he passes out (yes he's in our room and we have our own bathroom) ugh this is just so much fun ... 😂😂 any ideas on how to make it better. He's nursed and refuses milk. Not even breast milk in a bottle.
