My 13 day old daughter is very hard to keep sleeping at night. Even for naps. My 2 older children weren't this difficult. I've discovered she just wants to sleep on your chest or in your arms. I try to let her cry for a min, try to give her nookie. She spits it out... Cries even more. Pick her up give her milk she's completely quiet. Lay her down 6 mins later you get my point. We're at 2.5oz every 2 hours I just can't do the walk away let her cry for 15 mins thing. She's a newborn & I feel like she needs her mama. Any advice or tips
