LO2 is 4 months old and over the past 2 weeks, has started to fight the swaddle. He'll cry for about 5 to 10 minutes when I swaddle him for bedtime, but then he usually calms and falls asleep. But now he's waking up multiple times in the middle of the night and struggling to get out of the swaddle, and the only way I can get him back down is to nurse him. But even then he'll fall asleep, I'll put him down, and 5 minutes later he's awake and trying to escape the swaddle. He also shares a room with LO1, who is 2.5, and I don't want him to wake her up.

I bought a zipadee-zip and put him in it last night, but then he would wake up and flap his arms around like a bat. So I'm not sure what to do now...is he not ready for the zipadee-zip? Last night I just wound up swaddling him again over the zipadee-zip. He hasn't rolled over onto his tummy yet but can roll over onto his side.

Any advice or suggestions from the hive? For those who used the zipadee-zip, how long did it take for your LO to get used to it? Is it time to sleep train him? I also can't tell if the swaddle-fighting is also a sleep regression...but I need my sleep again!!
