My baby is 14 weeks/3 and a half months. We co-sleep with his snuggle me/dock a tot. I’m trying to get him used to napping in his crib but his startle reflex is so strong and he just can’t get in a good nap. I’m trying to make this transition sooner rather than later though. The way I see it, I don’t want to use the dockatot in his crib because he’s going to eventually stop using it anyway especially when he starts to roll over. Which he hasn’t done yet. What are some tips. Please help!
