My baby boy is almost 3 months here and for the past 3 days he has broken free of his swaddled blankets at night. We use a normal swaddle blanket and keep his arms down then wrap him once more in a thicker warmer blanket as well. It gets cold in his room since it's the middle of winter here otherwise we would just use the swaddle blanket. He has been sleeping through the night from 9:30-6:30 up until this started to happen. When he breaks free his arms are all crazy which we call them spaze hands because they r all over the place which wakes him up.
I thought about about keeping his arms out and just wrapping his lower part but like I said his arms/hands go all over the place and he does not sleep good then wakes and cries. I wrapped my other children up until about 5-6 months which worked perfect but with this little guy I'm not sure what to do!?! Should I buy one of those Miracle blankets or would that be a waste at this stage? Any other tips would be greatly appreciated since I want my nights back to sleep! Also, we wrap him really tight thinking he won't get out but that has not helped.

Re: Swaddling
She had been fully transitiond out of a swaddle until the wicked 4 month sleep regression hit. Now she is in a merlin's magic sleep suite...which really is magic
At the beginning, he did get startled with his arms, but he got used to it.
DS was never a good sleeper to begin with. So his sleep pattern didn't get worse when we stopped swaddling. It took a week or so for him to not wake up when we put him down. He's almost four months now and always sleeps with his arms up.
