14 month old breastfeeding & baby #2

Meghan

I am almost 5 weeks pregnant with baby #2! We are excited but a bit nervous. I had planned to stop breastfeeding at 1yr but my now 14 month old still nurses to sleep and co sleeps halfway through the night when he wakes up. I need tips for weaning and getting him to stay in the crib all night. Would like this transition done in the next 2 months or so that way he has time to adjust and it's not a shock when the new baby is here in April.
