My husband and I share a child together and I also have a step child, my husbands older child. The children are 3 and 11 so quite a large gap.
It's really starting to bug me that I never seem to be able to have a conversation with DH about our child without him swinging the conversation back to his 11 year old somehow.
For example showing him pictures of 3 year old doing X Y of Z just becomes aw I remember when DS11 did x y and z, he was really good at it, he learnt it really quickly, I've probably got a picture here somewhere hold on I'll find it and show you, oh look here it is etc etc.
Or 'Dh what shall we get 3 year old for Christmas' becomes a quick 2 min conversation before he starts going on and on about what he's going to get his DS11.
It's annoying. Sometimes I just want to talk about our child, sometimes I just want to share our child's achievements or cute moments without making it all about DS11. Sometimes I just want to look at a few pictures of our kid without also then having having scroll through reems of pics of DSS too.
