My little boy is 4.5 months (I'm not sure if we've hit regression yet or not) and so far I've only been able to get him to sleep at night while swaddled in those velcro swaddle blankets.
But now I need to get him out of them - he's far too big for them, and he can roll over. I bought one of the Love to Dream blankets which holds his arms up by his head and where the arms can be zipped off to transition him into a sleeping bag. However, when he's in it, as soon as I go to put him down in his crib, he wakes up and starts crying. After trying for over an hour tonight, I've given up and put him back in his swaddle. I'm exhausted, and I guess he is too! Any tips to make this easier for both of us?
