So I went on my Thursday walk and when I put Peter in the stroller he was awake. I thought that he might stay awake so I didn't swaddle him before putting him in, but I brought the swaddle blanket just in case. About halfway through the walk he started to cry because he had fallen asleep and kept waking himself up. So we stopped and I swaddled him in his swaddle blanket and he instantly stopped crying. I knew that's what he wanted but I didn't expect him to immediately quiet down. It was amazing. The ladies that I was with were all seriously impressed that swaddling worked so quickly and so well. Heck, I was pretty impressed too!
I only wish I had more that fit him so I could rotate them while one is getting washed. Though I do have fleece and flannel and I could probably make one myself.
