Sleeping pattern

I must say getting enough sleep is becoming a big priority in my life as I am not getting enough. Cherise is sleeping much better since she moved out of our room, but Jean-Marie is the big screamer. She will start waking up from 11h00 and scream. I started giving her a bottle to sooth her but at 03h00 in the morning she just doesn't want it anymore. Just when I think I can not take another sleepless night Jean-Marie will sleep right through. Parenting is such a pleasure sometimes!
