Introducing foster children to the family

Has anyone welcomed foster children into the family when you already had kids? Any tips on what I can do to help my own children and the foster children adjust? I have 6 kids of my own and 4 more would be joining us. This is a foster to adopt plan. These 4 children are my estranged sister’s children and she’s been missing. This isn’t the first time she has abandoned her children and will not be able to reclaim her rights as a parent. We’d like to keep them out of the system so we are welcoming them into my home. We’ve never met the kids. They’ve been in and out of foster care many times. For their entire lives they’ve bounced around between foster homes and living with their addict parents. They’re coming to us with some serious stories. I don’t know how to avoid making my kids feel left out and forgotten while providing attention to these 4. I don’t know how to make my nieces and nephew feel welcome without being overbearing. They are 11, 5, 4 and 8 months old. Help me!! I’m looking for any advice, ideas, tips I can get, but here’s some specific questions:1) should I arrange the bedroom situation so my kids will be sharing rooms with them? Or let the 2 of them share a room? Baby will be in the nursery with my newly turned 1 year old.2) Would taking a trip to Disneyland to welcome them to the family be too overwhelming or is that a good way to get them excited about us and get everyone bonding?3) when is a good time to introduce them to extended family? My husband and I both have large families and we are all close. Should we just wait until they’re settled because it would be too much?They’ll be here Friday!
