18m age gap, DS is 15m, DD is a few months off 3. They both pretty much ignore eachother! There's the usual scuffles over toys but I find it more sad that they just have no affection for eachother at all. They don't want to kiss eachother goodnight, rarely cuddle, today I was dancing with dd in the kitchen and ds wanted to join in and I asked her to hold his hand and she point blank refused. We get a lot of incidents like this. He's now quite hostile toward her!
They will grow out of this right? Am I doing something wrong?
