There was me being all smug thinking we had skipped the 4 month sleep regression, but oh no. And upon more research it's actually much more common for it to occur at 5 months instead of 4! Last night my daughter wouldn't sleep until 10pm, she then woke at 12, 12:40, 1, 1:38 & then she wouldn't sleep unless I walked around the house. Once I knew she was in a deep sleep I put her down & then she slept probably 3-6 and back down again until 9:40. I think she was so tired she just couldn't be bothered to stay awake any more!! I'm a zombie! This all started after her final lot of shots, I'm talking literally to the day. I don't believe in CIO methods, no offence to anyone else but it's just not for me. But I need some serious advice. Oh and she will not sleep unless she's with me which is complicating things even further 😩😩 this having a baby lark is a lot harder than it looks!
