My 6 month old was waking often so I read the Baby Whisperer and immediately did pu/pd for a couple of nights. I stuck to it strictly and by the end of a week it had really worked! sleeping through the night for a few weeks - bliss! And then we had 2 weeks of illness when I fed her often in the night, followed by a few days of pu/pd trying to get back on track before we went on 2 weeks holidays. Now she is home, 8 months old and waking at least once in the night. During the holidays I took her into my bed to avoid waking the whole house, but i didn't feed her between 10pm and 5am(ish). I now am trying to do pu/pd to resettle her but it feels like she knows its a trick and just cries and cries longer than ever. Last night I was determined to succeed but finally fed her at 4.30am after 1.5 hours of crying, because by that time she had started sucking frantically on my finger and I think she really was hungry. I know not to pick her up now, so i just try to tuck her in with calming words and sit by the cot. Whenever it seems like she's really asleep there's another wake up and screaming starts all over again -help!!!
