Sleeping habits

I am almost 8 months pregnant and have a son that is almost 2. His father has him so spoiled at night with sleeping I am at my wits end.
My son won't sleep in his bed. My husband and him sleep in the recliner together every night.

I need you help on how to break this habit now for good before the new baby gets here.

Any sugestions?

I don't have any suggestions, just wanted to say good luck. My 2 yr old still sleeps in my bed and my 4 month old is right beside it in his bassinet. It was SO hard when we came home with the new baby, b/c Jada wanted to still sleep on me (I had a c section). Now she doesn't sleep on me just beside me and up under me most of the night.

habits are so hard to break, but just stick him in his bed and keep putting him there if he gets out. It'll probably take some time but just stick at it
