She is in combination feed, twice in the day formula and then post work I give her one Brest feed and then post dinner Brest feed to go to sleep. Since 3-4 days she wakes up in the middle of the night and cries incessantly for two hours and asks for feed after breastfeeding she is till hungry and doesn’t want to be kept down. Then I prepare formula in the middle of the night an feed her. Sometimes she sleeps and sometimes she doesn’t want to be put to bed. Those nights she keeps waking up almost every hour for a Brest feed, what should I do? Why is she crying?
