Help!!

Any advice on welcoming a new baby with a jealous step child?

Ever since her father and I have been together, it’s been issues after issues. She’s disrespectful, lies over everything, etc. It seemed to get a little better as time went on, but we recently got married and found out we were expecting and it seems things have all of a sudden gotten worse than they’ve ever been.

The baby is due right around her birthday. We only have a 3 bedroom house. So either way someone will be sharing a room. We’ve decided that if it’s a boy, she will share a room with my daughter but if it’s a girl, she will share a room with the baby. I don’t think it’s fair for her to have her own room when she’s only here 4 days a month. It’s what we came up with as a couple. She’s 9 and my daughter is 7.

It’s recently been brought to our attention that she’s mad she will have to share a room (up until they moved here, she always has shared a room with someone, even at home, with her older twin brothers) but with only 3 bedrooms there isn’t any other options. Also, she has said that if the baby is born on her birthday she will refuse to come over for awhile.

I am due January 18th, her birthday is January 13th. I will have to schedule a csection due to my previous csection which is the Saturday before her birthday, depending on scheduling we may have to wait until the Monday.

How do we fix things? She lies about everything, she’s malicious, disrespectful, it’s getting worse every time she comes over. There’s major jealousy issues with my daughter (my daughter doesn’t have her dad in her life so her and hubby are close) and it seems it’s going to be bad with the baby already.
