Have I messed up by sharing a bedroom with my kids?

Hi there guys. 29 yo single mom with a 4.5 yo and son turning 3 this month. Long story short, my daughter had her own room as a baby up until about 1.5 years I think (too laZy to do the math right now, lol) this is around the time I escape her abusive father and gained custody. I was pregnant during this time.We moved in with my folks. Have been here ever since. 7 family members in a 5 br, so there's space but when we first moved in my mom was against altering her guest room and I won't lie, it felt comfortable and safe knowing my children, though in their own separate beds, I knew they were safe. Linked to the trauma I guess.Now it's been 3 years and I have pland set up and in motion off next year to move. Finally got everything lined up... And now that the kids are older I'm starting to think falling into the comfort felt good at first but now I may have done them a disservice.I feel like such a goof up. With our recent therapy and self reflection I'm trying to move past things and I guess this thing I thought was small back may not have helped them moved past things either... I feel guilty.I'm in the middle of getting things together to transform the guest room into a bedroom they can share (still convincing my mom... ) I was originally planning to get a 2 br, now I'm wondering due to the circumstances should it really be a 3 where each have their own room? Is that normal for that she group (she would be 5 going on 6, he would be 4 or almost there) via /r/Parenting https://ift.tt/39mxYr1
