Sexually abused as a child, I don't know where to post this

When I was a child, maybe up to age 8/9, I had two cousins, both girls, who would touch me while I was sleeping, or ask to do things to me and I was so little I didn't know what was going on, we were playing "mommy and daddy" is what one of them told me. They were both much older than me 11 & 12, I never told anyone what was going on but I felt like it was wrong so I just stopped spending the nights with them... Well now I'm having my own baby and one of those cousins keeps making stuff for her, keeps asking about when she will get to meet her, stuff like that and it makes me so uncomfortable, I think she thinks I forgot what happened but I don't, I don't even really acknowledge when she says she got my baby something, is it wrong for me to want to keep my child away from her? Do all cousins do these things? 😔💔 I feel like this is bringing back so many feelings I thought I was healed from.
