DS is just coming up to 8 weeks. Yesterday and today he has fed a lot more than usual which I was putting down to the heat. However today he fed for 3 hours constantly on the breast (did swap sides) had a half hour break and then was back on. He normally settles in his cot around 9pm and will sleep until 1/2 am but last night and tonight he just doesn't seem settled? Is this to do with my milk and he's not satisfied or is it the heat etc? I'm now worrying thinking he doesn't seem to have put much weight on either but he's due to be weighed on Wednesday. Not sure if I should bother the HV or not or if I'm being paranoid!
