This is driving me to despair. DS is 4.5 months and wakes so frequently. During the day he only ever sleeps about 20 mins, if I'm lucky, before waking. At night it's every 40-60 minutes. He is so agitated all the time. It's like he never relaxes. He doesn't sleep on his back, he just flails around and ends up in a right state so he sleeps on his side. Swaddling doesn't work. He has a dummy, it falls out all the time and he wakes. White noise doesn't work. Sling does work but I can't have him on me all the time and obviously this doesn't work at night. Please don't tell me it's the four month regression as he has always been like this, you have to be sleeping to then regress from it. The longest he's ever slept is about 3 hours and that was overnight. He hasn't done that for weeks and weeks now. Please help, I feel like I'm being tortured.
