My baby girl is 3 weeks old and won't settle at all when I put her down. She's ok for 15 mins or so then grisles and cries, then when I go to pick her up she's asleep in mid air before I can even cuddle her, back down and the same again.... tried the tshirt thing, holding her hand, leaving her be for a while to whinge it out (but she just gets very upset), I've had 8 hours sleep in the past 3 days as she's constantly on me..... don't know what else to do
