@Kerry my girl does the same and boy difference is she wakes her self up. There must be a reason why they are doing this.
Mine is super active sleeper, you'd think she was awake, wriggling and making loads of noises lol
Could be active sleep
I know it all too well, could just be an active sleeper, mine toots a lot during her sleep too😂
My little boy also does this sometimes in the night! I pop in a dummy and it tends to stop him making noises…most of the time but not all! x
