DD is deeeeeep in the 4 month regression - waking every 90 minutes and often refusing to sleep in her cot.
I can (just!) cope at the moment if I know that this is temporary, but my worry is that I have read conflicting things about how it could get better.
Some experts say it's important to not to get into bad habits during the regression, so to push back on co-sleeping ect (as I don't want to do it long term). Others say it's not the right time to make changes and you should just ride it out.
So what's your experience? Did your 4 month babies just magically get better, or did you have to work at it?
