My LO is about 4 1/2 months and sleeping has always been an issue. With the 4 month sleep regression and breaking out of her swaddle, it has been even worse... But we found the silver bullet...putting her to sleep on her stomach. It's a dream. She can roll belly to back and has great neck control. Of course, every website and pediatrician tells us not to. Anyone else going against the grain and allowing stomach sleeping? Personally, I think our parents were onto something.
