How can I make my 3 children happy about a half brother?

You need to tell your kids that what their father is telling them is a bunch of rubbish. You don't even need to be blood related to be a true family. What about all the families who adopt (officially and unofficially)? How many families have an Auntie or Uncle who isn't even their biological relative? Family is about love and nothing else.

I come from a large family of 7 children and NONE of my siblings are my "whole" sibling, they are all half. If you told one of my brothers or sisters that I wasn't their real sister then you would probably get slapped silly.

My advice would be to have your children talk to other families who have half siblings or adopted siblings. They will hopefully realize that there really is no difference.

Good luck!

They are old enough to understand that the baby is in the same tummy they were. They know they will all have the same mom. Your ex trying to alienate them is disgusting and maybe prosecutable. Ask the lawyer. This could be construed as mental abuse.

Perhaps now is the time to explain jealousy in the most adult, non-judgemental way possible.

Maybe they can tell him, he doesn't have to love their brother, but they will. or that they know you two aren't in love anymore, but they still love you both.

Explain that babies are supposed to come along when people are in love, and just like when you loved their dad and had them, you now love bf too, and here comes baby.

Are they having a problem because you are not married? Worried baby's daddy will bolt? I'd address that too.

Well first off do you have a parenting plan through the court or do you have legal physical custody? Because if you do , most of the parenting plans say that you guys cant talk bad about each other or thier family and if you do it is a violation of the parenting plan and he can get in alot of trouble with the judge. Also if you can get a tape recorder and have him admit over the phone or when you talk to him (just hide a small tape recorder on you) you will have proof to back up your story to the court. and then just take him to court over it because that is just wrong! My children have a step-brother and his mom was the same way when she found we were having our first child together.

I know this may seem manipulative, but i would try to reduce the time the kids spend with the ex. They're just getting bad ideas from him, but at the same time don't try to force your kids to like the baby, it's up to them. I would stop the ex seeing the kids as much and then just treat the kids as normal and they will feel fine again if they like your boyfriend.

Tell your kids that it's not true, but even if it was they can still like him like any other kid that they'd meet.

Your ex is a jerk. Have you yelled at him? You should.
