At 4 months, babies are going through a ton of developmental changes/leaps, plus probably a growth spurt thrown in, and becoming more aware of the world around them (hence when they wake up, it's not as easy for them to go back to sleep). I would give your LO a few weeks to see if she comes out of it on her own (which some babies do!). Otherwise, you can decide whether or not to sleep train again. </p> https://boards.hellobee.com/topic/cio-amp-4-month-regression#post-882351 Tue, 25 Jun 2013 10:57:47 +0000 mrsmate 882351@https://boards.hellobee.com/ <p>At that age babies are still growing and changing so much, there could be lots of reasons it's not working. At 4mo my LO still needed night feedings, so I just accommodated her until she was night weaned. We didn't start sleep training until well after 6mo and we still had to retrain several times due to illness, teething, vacation, etc. I don't think such young babies can self soothe vey well. </p> https://boards.hellobee.com/topic/cio-amp-4-month-regression#post-882255 Tue, 25 Jun 2013 10:26:46 +0000 Corduroy 882255@https://boards.hellobee.com/ <p>DH &amp; I sleep trained LO at 3.5 months. Now at 4 months and one day I'm pretty sure we're dealing with the 4 month sleep regression. From what I've read on the boards it sounds like everyone's sleep training goes out the window during the regression. </p> <p>Why is that? Does CIO stop working? Did you stop for your own sanity? </p>
