I have a 4 week old dd3. I didn't use the contented baby book with my first 2 children, but am having a hard time at night with my third and was confused about what to do. My dd3 was 8lb 11 at birth but seems to only take around 2 oz a feed. She still seems very sleepy during the day, so sometimes I have to wake her if its gone 4 hours since the last feed. Needless to say she's up several times in the night and at times won't settle for over 2 hours. The other night my husband and I were with her for 4 hours trying to settle her (she is formula fed btw). I live in the USA and my paediatrician says to let her find her own schedule, but when you read the contented baby book it says about waking them etc for feeds and not letting them sleep too long. I can relate to this, but when you have 2 other kids to run around after, how are you supposed to follow this strict routine? Anyone got any tips? Sometimes my dd3 just won't be kept awake!
