My daughter is 12. In January her uncle started giving her guitar lessons as she really wanted to learn. He has been playing for years and sometimes teaches lessons, so when he offered to teach her for free, it was too good to turn down. The lessons are at our house. She's really been enjoying it. I still offer him money, but it's always a firm no.
He took her to see a band that they both like in March. His wife was also there. DD came back with loads of merch. I was thankful but told him he didn't need to do all of that! I felt like it was really cool they were bonding so well though. DH loved to see it as well.
He has bought her quite a few things now other than that merch. Like a necklace, posters, figurines, he even offered to buy her expensive trainers when she asked me for them in front of him. I said no to that one, because me and DH already decided she didn't need them. (girl has a lot.)
DH and I check her phone regularly. They text each other probably once or twice a week. It's brief and they just send each other memes and links to music they like. I haven't seen an actual conversation with them, so think I'm happy with that.
Yesterday he was at our house. We were all in the same room talking. DD went and sat on his lap and it made me feel uncomfortable. Only because she never sits on an adults lap anymore? I wasn't going to make a scene or anything, so I just made an excuse and asked her to come help me with something in a different room. When she went back into the room, she didn't sit on his lap again.
The same day, he dropped into conversation about how "Asian and half Asian girls are the most beautiful" he looked at DD and she giggled. DD is half Asian. I'm starting to feel a bit uncomfortable with it all. But I'm not sure if I'm being unreasonable? I don't want to break an innocent bond, but I feel like I missed some red flags and I'm now seeing them? DH says he just loves his niece and he doesn't think we have to worry.
