My little bundle of joy is almost 4 weeks old and whilst she's good as gold most of the time, nights are fast becoming a bit of a nightmare. She sleeps really well in the day but come night time she becomes really unsettled. She won't go down until later and later, starting with about midnight and last night not dropping off until 3am. Once she's asleep she sleeps like a dream and she's actually really good at dropping off. She spends hours dropping off to sleep and then her stomach will let out this huge growl and she wakes again. She has a dummy which settles her a bit and with this she drops off but what can I do about the tummy rumbles? We give her infacol and she's on cow and gate comfort milk, is it worth trying a different milk?
