I'm due on Thursday with DC1 😬. DH got exiled to the spare bed about a week ago, so I have a load more room than usual. However, it means I keep waking up on my back, probably a couple of times a night. Naturally, I'm terrified this is going to harm baby. Do I need to reinforce the pillow fort to keep me on my left, or do I just run with whatever can make me actually sleep at this stage?
