Thanks Jessmum
I don't think he's uncomfortable, not squirming too much. Just wont stay asleep. Finally managed to get him to sleep on my chest, still with alot of dummy popping. The child health nurse said it may be due to a wonder week, so will be emotional, not physical need. Thankfully he slept really well last night. I have tried the moby sling & after initial protest, he seemed to settle ok in it.
Thanks for replying and hope you have a great weekend
