I have 3 dcs and my dh died last year, it's been a struggle but we are coping. I've been keen to keep up their hobbies and channel their interests.
Middle dc, my dd, has always been close to her cousin (like sisters) and when her cousin comes over they are inseparable. This seems reciprocal as they both enjoy each others company.
Dd started playing tennis at the same club last autumn. Her cousin plays there and had said how much dd will love it there, cousin is a bit older. My dd is 10 soon and adores her cousin.
I understand that my niece has her own friends and is entering that teenage phase where she wants to seem 'cool'. Since dd started playing at this club her cousin actively avoids her, doesn't speak to her, even say hello.
Dd gets very confused and upset by this as is so used to the close relationship and things being different in private. I've seen this myself and for months tried to not say anything to dsis about it. It happened recently where dd saw her cousin coming into the clubroom and waved, smiled at her. Niece saw her, blanked her then walked in the opposite direction. I saw this too (I'm used to being ignored by niece!!). This happens all the time.
Dd very upset by this last night, wwyd? Maybe try to distance the relationship? We've even considered leaving the club. Dd would be just happy with a "Hi, I'm busy but great to see you" from the cousin.
