Help! First time mum here. My LO ( 3 months and 20 days) used to sleep in chunks of 4-5 hrs a night. For the last two weeks this went out the window and he's been barely sleeping 2 hours in a row. The last three days has been the worst where he will sleep 1 hour, feed 5 mins and then sleep again for an hour. This pattern would go on all night. I'm running on fumes.
In the day I've noticed he's started drooling a lot and has been sucking on his toys and Muslin aggressively. This has meant his poo has gone bright yellow, runny and diarrhoea. His naps also are very short in the daytime, Max 30 mins unless he's clinging on to me. He wakes up crying/ screaming most times.
Can it be sleep regression? Or early teething? I've tried Calpol, bongela, cool teething toys, putting him (safely) to sleep/feed next to me in bed at night. Nothing works, just lots of cuddles. Thanks! Very tired zombie mum.
