Noisy sleeper at 4 weeks

[brummum2]

My baby is just 4 weeks, sleeps well only waking for feed around 3am and the 6-7am but has just become a really noisy sleeper! She grunts, groans, makes high pitch squeaks like wheels squealing, it feels like it is all night!

Anyone else have experience of this as while she is sleeping well, her parents are wide awake!

Oh yes! That's why DS had to move out to his own room so early! Just turned 5 and still at it, just like DH! I pity his future wife/civil partner who will spend many hours wanting to smother him with a pillow.
We got an Angelcare monitor, which goes off if no movement is detected for 30 secs so we knew he was safe in his own room then left him to shriek and grunt.
