DD2 was born yesterday am. Since birth, she has fed almost constantly (I know this is normal. I BF DD1 until nearly a year). However due to a long labour I have slept 4 hours out of the last 72. We got home from hospital yesterday evening, went to bed and she was latched on from 10pm- 4am without a break. If she unlatched she screamed the house down. Did the same again today from 11am- 3pm. Has now been latched since 7pm with no sign of let up. I can't get through another night (third in a row) with no sleep. I just can't. What can I do?
