My first child is coming up to 4 months old. Up until now he's been pretty good. He is bottle fed, takes 7 oz ish per feed and once asleep (around 9pm) he sleep until 2am, sleep feeds and feeds again at 6am. Increasingly in the day and from around 6pm until 9pm he is getting really worked up. This started as whinging but is progressing into crying if I can't get him to sleep fast enough. This was bareable but my partner is back to work today (home weekends only) and I'm sitting here wondering how the bloody hell I'm going to get through the week. More and more in the day he's becoming over tired and working himself up. I feed him when he's hungry and put him to sleep if he's tired. But in the day there's no routine, it's all so hit and miss and k feel like I'm failing. Is all this unsettled behaviour my fault? I'm trying to bath him, change him and feed him at 6.30pm every night to get him to know it's bed time but honestly I'm just feeling like I'm totally winging this and getting it all wrong. Is he too young for a routine? How can I get him to sleep easier and avoid this over tired screaming?
