Six month old waking up every 90 minutes

[MsElisaDay]

First of all, sorry for the length of this!
My DS has never been what you'd call a good sleeper, but before last week had got into a pretty good "routine."
He'd go to bed at 7pm ish, feed at 11pm, again at 4am, and then up for the day between 6.30am and 7am.
Sadly, though, this bliss only lasted a few days.

For the last week or so he's gone to bed at 7pm just like he did before, but has started waking at 10.30pm, again at 1am, then about 2.30am and 4am.
I then breastfeed him at the 4am waking and he'll settle back down around 4.30am before sleeping until around 6.30am.

I don't feed him at each of the other wakings aside from the 4am one, and he usually settles down quite quickly, but he will not settle without me shushing him, and having his dummy.

If I wasn't back at work I'd be just going with the flow and hoping it would pass. However, being up so much in the night now I'm back at work is horrendous. It takes me half an hour to get back to sleep after he wakes, and then I only have perhaps an hour before I wake again.
He's in his own room and I'm loath to bring him back in with me and my DH, because DS is such a noisy sleeper that I barely slept at all then.

What I'm wondering is, why has he started waking so frequently, and what can I do about it?

He's BF (on EBM during the day now I'm back at work) although he has started drinking less milk throughout the day now I'm working - could that be it? He doesn't seem to like the bottle as much as the boob, though does still have at least four good breastfeeds from me over 24 hours.

His "routine" goes something like this:
7am - breastfeed
8am - baby porridge
Mid morning - EBM on waking from morning nap
12noon - Lunch. As much EBM as he wants, plus some veg puree and finger food
3pm - EBM
6pm - Breastfeed from me on my return from work, bath and bed.

Then two more breastfeeds, around 10.30pm and 4am

Any help would be much appreciated.
Friends' babies of the same age have been sleeping through for weeks, whereas I feel like I have a newborn again!

Sorry, should add he's almost exactly six months old, goes 26 weeks next week.

Hi there,

I have the same problem with my DD she's coming up to 7 months now. It's terrible and the lack of sleep is killing me!!!

I had a health visit a few weeks back where they checked DDs weight and height - everything seemed ok. Asked the usual questions re: weaning to rule out anything allergy related. Her advise was to see a doc in case she had acid reflux or an infection that was causing her pain whilst lying down. Apparently they can have no symptoms but when they put pressure on their heads when lying it can cause pain and that's what wake them at night.

Doc checked her over and it wasn't an ear infection. Got some baby gaviscon for her and that made no difference. Went back today for a follow up as she's still the same, his response was some babies just aren't good sleepers. I think my DD is going through a growth spurt as she's feeding a lot more during the day and once at night again, although the hv advised me not to feed her at night but it seems to settle her somewhat and I don't want to deny her food!

Maybe go to your GP to rule out anything major. If that doesn't help, then your child may be like mine and an unsettled sleeper. I have been assured its a phase and I'm hoping (and praying!!!) she gets over it soon as I like you am absolutely shattered its making me physically sick!

Good luck!
