I just want to second what Tigeresslady said - it can take a few sessions. I took both boys when they were tiny for colic and it helped J loads, but we had 3 sessions and the first few days after each were more unsettled.
I took A back a week or so ago for his sleep - he's slept really badly since he was born, and after last weeks session he slept through. His sleep was ok then for a few days, but its back to bad again - we're going back to the CO next week! x
This isn't flying, its falling - with style
