do all babie go through bad sleep regression?

[Murphyslaw21]

I'm just wondering do they all go through bad sleep regression? Or do some just have a bad week or two?

None of mine ever have gone through the mystical '4 month sleep regression'. The first two never slept, well or otherwise. The third sleeps like a dream. He's currently 4.5 months. I think the 4 month sleep regression coincides with first teeth, sometimes first solid foods, and baby getting bigger so more difficult to rock to sleep or moving more when lay down to sleep. It makes sense that sleep might be affected at this age. The wonder weeks describes a massive development leap at 14-19 weeks which also coincides.

None of mine have ever went through any sleep regression, I had never heard of it until I came on here and read about it.

DS and DD didn't do it. They're all different though. He was a bugger for nightmares at 5/6 years so it all evens out.
