Jealousy, toddler/newborn??

Our son will be 22 months old when his baby brother is born (in April).

He is a happy, well-adjusted, healthy kid who is particularly attached to his dad. (Momma is chopped liver....... it stings, but I love him anyway!)

He is very well sleep-trained, and sleeps in his own room from 7pm-7am most of the time.

The new baby, when he arrives, will co-sleep with my husband and I for the first while (maybe 6-8 months...?).

My concern is about my toddler being jealous or feeling left out.

If he realizes that the baby gets to sleep with mommy (and worse - with DADDY!!!) ... I am worried this will create feelings of loss, resentment, jealousy, and competitiveness.

I can’t have a conversation with my toddler and explain things rationally. He isn’t there yet.

At 18 months, he understands basic language pretty well, but hasn’t gotten abstract concepts yet.

For example, he can find his own belly button when asked, but doesn’t comprehend that I’ve got a baby inside my belly. He only has a half a dozen words of his own. (Juice, shoes, ball, boots, uh-oh, this, yes).

So I can’t really work with him or explain this on an intellectual level.

My question is .....

How have other moms handled this?

Did your toddler care about the baby getting to co-sleep?

Did you do anything to prevent your toddler from realizing where the baby slept?

Did you just let the toddler start sleeping in your room too?

How did it work out? Are you glad you handled it the way you did, or would you do it differently if you had to redo it?

Thank you so much!!!!!!
