Where has my gorgeous DS gone?? DS used to go to bed at 7pm and sleep until 11pm roughly and then have b/f basically in his sleep every 3/4 hours until morning. He would sleep in his cot. He is now 6 1/2 months old but for the last 3 or so weeks he has been screaming hysterically and neither me or DH can calm him down. I try b/f, holding him, putting him in his cot, co-sleeping, DH holding him but nothing is working. He just screams and he is exhausted and finally gives in to the exhaustion & sleeps. He is perfect during the day. Happy, playing, squirting around on the floor, sleeping anywhere between 1 1/2 to 2 1/2 hours after settling himself in bed without a single tear/cry/gizzle. But come night he screams hysterically for hours and then wakes up hourly. I follow exactly the same routine at night as during the day. Our room is extremely dark so I put my lamp on the floor behind my bed on the lowest setting just to put a little bit of light in there. He is wrapped. Our house has ducted heating so it's a constant temp. My older two kids are still up so there is still noise in the house like during the day.

I'm desperate - any ideas before I completely loose the last thread of sanity I'm hanging on to for dear life?

TIA
