She's 4 DC (including me
).
I slept through from birth really, best sleeper according to my Mum but most difficult 'child'
Dsister1 slept through from 6 weeks but before that slept in good chunks anyway.
Dsister2 slept through from about 4 weeks - I remember this well (huge age gap between us), as often my Mum would be wide awake in pains from a C Section and go downstairs so she didn't wake DSister2 with her tears 
Dbrother slept through pretty much from birth! Again, I remember all this as I was 16 at the time. Know something else? He transferred into his own room at 1 just as well as his sisters. DM was in so much pain with a hernia from C Section complications that I often gave him feeds etc. Never had a problem with any of them and good sleepers... if not excellent.
AIBU to accuse DM of hiding a secret? My own baby will be here very soon and I just know they'll be pants at sleeping
