Yes, we got someone in. We were absolutely at the end of our tether...it cost a fortune but we were desperate. She came to our house, observed our then 6 month old and diagnosed reflux.(Doctors had just said he had colic!)He was waking 5 to 10 times a night. She sorted out medication, then began sleep training. A camera was puton the cot so we could see what was happening,then she went in and said "sleepy time, night night" and went out again! She would go in and out sporadically, sometimes just saying those words on the monitor. The words were always the same, no picking them up, just a reassuring pat and then out. He screamed the whole night the 1st night, the 2nd night he slept 12 hours through!
It hasn't been an easy ride but at least we know he can sleep through the night now. He still wakes very early, (between 5am and 6am), but I guess that will get later as he gets older, like our 2 year old.It was worth doing though....
