hello.. my baby is 9 weeks old now.. she sleeps pretty soundly at night waking up for a feed after 4 hours. but during the day it is impossible to put her to sleep. she seems tired and does sleep in my arms or during feeding but as soon as i put her down in her cot she wakes up and cries. she sometimes is interested in playing and sometimes seems irritated.. plus she puts her hands in her mouth all the time even right after feeding.. is she supposed to have these sleep patterns? I am sorry for the long post but being a first time mom i am pretty worried that my baby isn't getting enough sleep.. In need of advice..
