Can you start swaddling a 3.5 month old? We stopped when he was about 5-6 weeks because he hated it. He would grunt and kick for 30-45 minutes when we would put it on and after a few nights of finding him busted out of it wearing it around his neck like a cape, we stopped. He sleeps amazing at night but naps are another story. It takes ages to get him into the nap because he flails and kicks and then he always wakes up after 30-40 minutes which I assume is his one sleep cycle. He's exhausted all day long. I wonder if swaddling him for naps would help keep him from waking himself up but would it even work this late in the game?
