hi, just wanmted to share with you all... have had trouble with 8 month old dd8 waking several times during the night, even waking regularly about 2 hours after being put to bed, my husband read an article which said 'white noise' can help babies sleep, not sure of the science behind it but last night we put her to bed as usual but put a fan on in the room, she slept straight through until 6 this morning without stiring at all!!!! I was very sceptical but glad we tried it. you can get cd's, apps for iphones etc with white noise but a fan is just as good!!! worth a try hey?....would love to know if this has worked for anyone else???
