4 month old suddenly terrible sleeper

3w ago1 min read

My son was a pretty decent sleeper up until last week. He'd go down around 7, maybe wake once to feed around 2am, then sleep til 6. Now he's waking every 2-3 hours and I have no idea why. We haven't changed his routine or anything. Checked for fever, he's dry, not hungry (at least not acting like it). Did I miss something about the 4 month sleep regression? Is this normal? My wife and I are running on fumes here.

Four months is when a lot of kids go through a sleep regression. Could be developmental, could be a growth spurt where he needs more calories. Try feeding him a bit more before bed and see if that helps. Usually lasts 2-3 weeks.

Sleep deprivation is brutal. Just know this phase won't last forever. Document what he's doing so you can show your pediatrician if it keeps up past a few weeks.

Have you ruled out reflux or anything medical? My daughter had a sudden sleep change and it turned out she had silent reflux. Not saying that's definitely it but might be worth mentioning to the pediatrician just in case. Could also be teething starting early but 4 months is a bit young for that usually.

Could be the 4 month regression or just a growth spurt. We went through this too and it eventually clicked back to normal. Consistency helps but also give yourself grace during the rough patches.

That 4 month sleep regression is rough, man. We're dealing with something similar and it's exhausting. Hang in there, it's temporary even though it doesn't feel like it right now.

My son did this exact thing around the same age. Turned out he was hitting that 4 month regression hard. White noise machine and earlier bedtime helped us get through it. Hang tight, it gets better.

The 4 month sleep regression is real. My son went through the exact same thing around that time. Pediatrician said it's totally normal but man it's rough. Hang in there, it usually passes in a couple weeks. In the meantime, try to stay consistent with whatever routine you had before, even if it feels like it's not working.

Is he rolling over yet? Sometimes when babies start hitting those developmental milestones they get super restless and their sleep gets disrupted. Could also be the 4 month regression which basically every parent dreads. Sending strength your way, man.

Check if he's got any signs of reflux or discomfort too. Sometimes that doesn't show up until a few months in. If he seems uncomfortable when lying flat, that could be the culprit.
