Struggling with the custody process

Long story short my husband had a baby out of one time sex with his ex high school gf. We have a 3 year old and a 1 week old and his daughter is 5 months old. They just met for the first time Tuesday. The mediator is making him have one on ones with the baby and this woman alone to get her to know him, i get it. But to go to her house to put her to bed while they sleep in the same room at her mothers house is beyond me. He has a wife and 2 kids at home this seems odd.

It has me so insecure and super anxious all the time. July 11th they go back to mediation to come to an overnight agreement.

I honestly can’t wait to get her here and no more one on ones.

However they want to do co parenting which is amazing, however hello you have 3 other people at home to think about too.. he can’t possibly make everything with his daughter when his wife and son and daughter have stuff to attend to as well.

Keep in mind he had to have a dna test done and told not to sign off on her by me over and over.

Yes i don’t care for the mother but that child is his and his kids sister. We live in the same town.

I bought her stuff included her in the girls bedroom. And ready for her to be apart of our life.

I’m just frustrated he believes the court is only looking at it as him the mother and the baby... umm you have 2 kids at home and a wife that should be factored in. Judge and mediator should look at it like is the wife ok with this, can you handle 3 kids alone. Hey other mother you ok with her being in your daughters life because that’s what is going to happen.

Am i wrong to want him to speak up just a bit and say i need to make sure this is going to work for my family as well? State things like i don’t feel comfortable going to her(the mother of the baby’s) mothers house to feed her in her mothers room to put her to bed. Her mother hates him.

They agree on 50/50 and to be civil which is amazing! Hoping that. Actually is what goes in writing in July. But i just think their expectations of him being able to make every single thing with the mother isn’t going to work. We need time alone, he has 2 kids to try to balance their activities as well. I would be taking care of her 99% of the time she is at our home so I would like to go to her activities as well and her siblings would too. It will be us as a family of 4 going to the events and the mother being there and i don’t think my husband is looking st it like that. The mediator isn’t either.

One day the mother will settle down and the step dad will be involved there’s no difference

Sorry for ranting just never been in this position and really need some advise.
