Leyla The farex discussion has been had in the later half of the month group and they all say it makes little to no difference to the sleep pattern.
I've found with DD that she wakes heaps and I was thinking that it was feeding she wanted as she was always willing to take the boob, but worked out after my Mum had her for a night and she slept from 8pm to 2am and then until 6.20am that the problem was wind. Do you take the time to burp DS after a feed? I was too lazy, she was asleep from the feed and I didn't want to wake her, but now if I burp her and then give her a quick topup to resettle she sleeps much better, when we haven't got other issues going on.
I must admit though, after midnight I will bring her into the bed with me and agree with Fire that part of it is they just want to be with you. Like last night, because I'm trying to get DS to sleep in his room rather than the nursery I started out the night in his room and when I went in and got DD for her 11pm feed, her little eyes lit up when I picked her up and took her to the bed. Putting her back in the cot only lasted an hour an a half, where having her in the bed from 12.30am onwards tends to make for better sleep as even if she stirs I'm not having to fully waken to attend to her.
Rest assured Leyla you're not the only one and with DS he wasn't sleeping through until he was over 18months and from 14 months he was on formula and solids, so i doubt farex makes a difference. All babies are different remember that and know whatever works for you is the right thing.
