Sarah, sorry I have no advice, but i only wanted to tell you that Lily has been the same for about a week. She's been waking at about 3am for a party and takes about an hour or so to get back to sleep. As well as 2-3 other wake ups for her dummy. She will NOT have a feed at night now and cries even more if I try to give her one. Though she's sleeping well in the day probably cause she's sleeping so badly at night. So sorry no advice, but just some sympathy, and maybe to tell you that it is probably just a phase at this age?? I hope he improves for you soon.
