Hi all,My 5m old lo keeps on waking up at night within half hr or a hr from few days.As I nurse he sucks and sleeps and if I don't allow to nurse he cries becomes fussy.i know he isn't hungry.He use to nurse twice in night before.Is he getting in the habit to suck and sleep like a pacifier?I use too breastfeed him in sleeping position.Is that causing problem?Whole night I'm awake and my nipples pain.If his father takes him he's cranky.
