Right now the girls are sleeping in their swings. They are eight weeks old. Kaitlyn sleeps through the night from 10 PM until 6 AM 3 to 4 times per week. Hailey wakes up one time around 3:30 AM every night. I feel like I need to start getting them in their crib. But the second I lay them down In their crib they wake up within five minutes. Where do you put your babies to sleep and what age do we need to transition them to their crib. Also when I put them in their crib drowsy but awake they freak out. HELP!
