Baby keeps coming off the breast

[HelenF35]

My baby keeps coming off the breast then wanting to go straight back on. Any ideas why?

Check latch. Is baby's nose constructed by breast tissue? Could be coming up for air!

Latch seems fine, his nose is clear. I tried him on the other boob and he fed for a few mins and fell asleep

My daughter does this if she has wind. She will bob on and off and sometimes cry in frustration so I take her off for a bit, rub her back etc and try again... She's recently been having a growth spurt (3 weeks old) and I think sometimes she is suckling for comfort but isn't actually hungry. Could it be something like this maybe? How old is your son?
