Our DS (5 months) has never been the best sleeper. However from the 4 month mark things have been deteriorating. He's gone from waking up twice a night for a feed (which felt entirely manageable) to waking up between every 45 mins - an hour from the point that he goes down for the night, until morning. I'm assuming that he's waking up between sleep cycles and then not self-settling (which he was actually doing previously and still does when we put him down sleepy but awake to go to bed).
I was doing the majority of the night wakings during the week as DP is waking up for work at 06:30am, however he's been great helping out this week as things have been getting progressively worse. We're both so exhausted and feeling pretty directionless. This feels more difficult than the newborn stage.
DS has a solid nighttime bed routine. He has a bath between half 6/ quarter to 7, a feed in a dimly lit room and then he self settles in his cot. We've started giving him a feed at somewhere around 10pm before we go to bed and then he has one more feed during the night. However around these feeds he's just waking constantly. We can sometimes settle him by turning the hairdryer on (we've tried white noise apps which don't seem to work), otherwise we have to pick him up for a cuddle. Shhing/ patting etc don't work.
I'm so tired this morning I could cry. Can anyone give me any kind of advice? Or even just some reassurance? I feel as though we must have gone wrong somewhere and I'm starting to beat myself up about it.
Thank you
