My DS is 6 weeks old, and sleeps beautifully during the day. At night, though, it's another story. He sleeps but he strains and grunts and is gassy all night, to the point where the neighbours (we're in a flat) can hear him. He's a little bit awake during these times, but pick him up and he falls right back to sleep.
My question is why is he so noisy and gassy at night when during the day he's fine?
I don't know the answer but remember it well! DS2 would spend the second part of the night grunting and groaning and I was crazily googling trying to find out why! I even recorded him once to show the HV Looking back I think it must be something to do with their stomach maturing a bit. As he got older it just stopped and he never does it now at 9 months.
