Baby won’t sleep after jabs a week ago

[Emma543]

Hi all
my 9 week old / almost 10 week old went from almost sleeping through the night and waking for one feed, to having her jabs last Thursday and now only sleeping for approx 4 hours intermittently. Anyone have any experience of this?

i know it could be a coincidence and not related to her vaccines but I’m so sleep deprived and completely fucked off that I feel that they have completely disrupted her I can’t carry on like this. I’ve checked she’s not hungry, cold, wet. When I pick her up and lay her on my chest she stops but as soon as I try and put her back down it begins again

i now can’t get her down until 12am, she woke up at 1.30 crying but I did actually manage to settle her back down, fed at 4am and I have been trying to settle her back in her crib is ever since but nothing is working. This is a baby who before jabs would go down 10pm-7am with a feed about 3am only.

anyone else experienced this or have any ideas? Thankyou :(

Sorry to say that's it's usually around this time they start to develop their circadian rhythm so she's gone from spending all her time in deep sleep to going from light to deep sleep and doesn't know how to stay asleep so she's waking up in the light sleep phase and is pissed off.

It's this circadian rhythm change that leads to the 4 month sleep regression.

I have a nearly 11 week old and she had her jabs on Friday and has gone from sleeping 6-7 hours back to 3 hours. Not bad but not great when you've gotten used to longer stretches!

I did wonder if it was the jabs as she had 48 hours where she was very unhappy but like pp said there's also the changes in circadian rhythm at around this age as well.

I am going to give her a bottle of expressed milk before bed tonight to see if that helps lengthen the first sleep but like everything with babies it will soon change so I'm just riding it out apart from that.

It will just be the sleep regression that comes anywhere between 8 and 14 weeks

My 12-week-old was sleeping 2 or 3 hours at a time, then from 9 weeks just suddenly began waking every hour most nights! He’s still doing this now a few weeks later. I’m not sure if it’s related to his 8-week jabs - I know another lady whose DS had the same switch to 1-hour stretches after his 12-week jabs - but, as others have said, it may well be his circadian rhythm kicking in.

After a whole lot of stressing I’m now trying not to worry too much about it, rather than hoping to fix it, and see if anything improves over the next month or two before I consider trying something again. I’m holding out for the 5-/6-month mark when he may well be sleeping better already and, if not, will be old enough for some form of gentle sleep training if I can’t cope with the sleep deprivation anymore. I hope yours settles back to their old routine soon!
