I had a really unsettling experience today and I wanted to gauge opinions.
My husband and I took our 3 year old daughter to soft play today. We were sat on a couch, between my husband and I we were playing/watching our daughter. A father and his 2 daughters sat near us. I struck up conversation with the father. His 2 daughters were 12 and 13. His 12 year old started to interact with our daughter straight away. At first I was a bit surprised as she was very forward and stroked/picked our daughter up which our DD responded to, seeming at ease. The 12 year old then asked if she could play with our daughter and I said yes. I was watching them but the soft play was fairly large. I thought there was only one entrance/exit so wasn't too anxious as I could see if my DD left and continued to chat with the father. After about 5 minutes I got up to look for my DD and I couldn't find her. I came back to my DH to get him to go into the soft play to see if he could find her (I have a mobility/pain disease which limits my movement). He couldn't find her either - I got up straight away and as soon as I got to my DH I saw my DD come out of the toilet with the 12 year old. The 12 year old said she washed her hands. I asked whether my DD asked to use the toilet, the 12 year old seemed a little guarded. DD seemed fine showing me she washed her hands. DD wanted to go back to play with the 12 year old. I restated to the 12 year old that if my DD needed the toilet again to come get me or her dad. My DH and I took it in turn to then watch them both. I then went to the toilet and when I came back I could hear my daughter saying mummy, I came out and saw my DD was looking for me. The 12 year old was trying to encourage her to continue playing but I could see my DD wanted to leave. So I scooped her up, said bye to the father and his 2 daughters and left.
This happened about 8 hours ago and I still feel very uneasy about it all. Effectively for roughly 10 minutes I had no idea where my daughter was.
So AIBU and overthinking it or AINBU?
