Not latching at night

Just Me • Have a 4 year old daughter and a Newborn GLOW baby girl born 22/04/15..so in love 💕
Anyone else's baby the same? My 9 day old will latch in the day but at night she just won't latch at all and I have to give her a bottle (my expressed milk not formula). I end up waking up soaking wet through because she hasn't fed from me in the night it's awful, that even with nipple pads on ect. I don't know if it's the bed making the positioning different from the day time when I'm on the sofa of not but she just doesn't latch...
