Hi,
I would really appreciate any thoughts or suggestions about our gorgeous 4 month old DS's sleep patterns.
He used to sleep for about 5 hours after settling in the early evening, and then wake up about three times in the night until we got up at half seven/half eight-ish in the morning.
We thought that was hard at the time! 
Now he wakes up about every hour and a half. I know 4 months is supposed to be a growth spurt, and possibly a time of sleep regression, but what concerns me is that he doesn't seem hungry when he wakes, he just wants to latch on and then immediately falls asleep again.
We use a dummy at night and for naps, which calms him and helps him drift off to sleep, but he often pulls it out and cries furiously as we try to settle him. Also, if it drops out while he sleeps, he wakes up. So the dummy doesn't seem like the answer, although it certainly helps us in the short term, to help a very cross over-tired little boy get some sleep.
We went away to PILs over Christmas and this probably messed up his sense of routine too.
He has one bottle of formula before bed - since his sleep changed we have tried him on Aptimil Comfort because we thought maybe trapped wind was the problem, but it doesn't seem to have helped (two weeks now). Maybe we should try dairy-free?!
Currently we co-sleep for part of the night because after a few settlings I just get too tired to keep battling away at the cot-face
(is a three-sided bedside cot).
So....if anyone has any advice or thoughts/suggestions that would be great.
Also, I have read good things about Jo Tantum's methods - can anyone tell me basically what she says? And if you've had good results?
Thanks!
