Anyone a first time mom... with step children?

Jessi

My husbands children are 15, 13, and 10. They have already expressed that they aren’t keen on the idea of us having more children. The older two are especially bothered by the noise and the change, and the youngest WILL have a hard time not being the “baby” anymore. 😒 Any tips on how to tell them after the first trimester to lessen the blow? Thanks ladies!
