I have two DSC. One is a teen and one is 10.
I really like the older child, they are lovely, considerate, kind, fun to be around, chatty and just generally easy to look. Sure there is the usual teen attitude sometimes but on the whole they are really well behaved and we get on well.
But I really really struggle to like the younger one. In fact admittedly I don't like them at all. Everything they do grates on me. They are moody, selfish, barely engage in conversation other than to be rude / ask for something, whinge about everything, wind their sibling up (Inc teasing our younger children too). I just find their presence annoying put bluntly and internally roll my eyes whenever they are around.
I try so hard to be exactly the same way with them as I am their older sibling but I get barely anything back. I'm not new either by the way I have been around since they were a lot younger. DSC10 is exactly the same with their dad and mum apparently too.
It doesn't help that my husband thinks they can do no wrong either and babies them ridiculously.
I'm finding it hard to turn a blind eye to normal child behaviour like I can do with the older one and my own, everything they do bugs me even when it's "normal" misbehaviour or be subjective when it's an issue between the two DSC, often finding myself wanting to side with the older one even if they aren't always in the right.
I don't know what to do, I have tried so, so hard and I think that shows through the fact that I have a lovely relationship with my older DSC but I just cannot seem to bond with or like the younger one.
It's completely shit to feel this way I know. And yes I'd be heartbroken to know someone felt like this about my children. But I just cannot seem to like them.
