LO is approaching 16 weeks and for the past 6 weeks or so has been waking up from naps hysterically screaming. There’s no stirring or anything, he screws his face up/frowning then within about 10 seconds, even before he opens his eyes, he’s screaming. Thought he would phase out of it but it’s pretty persistent. He’s settled quite quickly with some comforting & cuddles, usually within less than a minute. Anyone else had this problem? It’s almost as if he’s having nightmares, but surely he’s too young for that? He wakes up from his night sleep in the morning happy as anything & smiling away at me from his next to me, it’s literally just his naps. Aware we’re approaching the dreaded 4 month sleep regression 🫣 TIA x
