How do you get your baby to sleep?! LO is 4 months and she's always either nursed to sleep or fallen asleep in the ergo. What is your nap routine like? Baby girl sleeps well - 2 3-hour naps and 2 catnaps before sleeping 9-7 with 1 MOTN feed - so I'm really afraid to change our routine but she can't do this forever. I also have a 20 month old running around so I can't always sit in a dark room and nurse for 20 minutes. TIA!
