I have 1 dd (4) and oh has 2 ds (2 and 5). For the most part they get on. For example bedtime routine and mornings.
However if we spend the whole day together, perhaps 40% of the time they do, 60% the time they don't.
Spending the whole day together on a weekend is pretty infrequent though due to the days we each have the children. When they do spend time together they are all rather excitable because it's not a daily occurrence - my dd especially as it's a 'break' from being on her own.
The 2 boys are used to have a sibling around all the time, the sharing and the playing, but my dd has been used to being an 'only' for so long that I think she struggles.
She wants to mother the 2 year old a lot. She looks after him constantly, but he starts getting agitated/whine as he doesn't want to be looked after and will push her out the way. She doesn't take the hint and will continue to 'look after him'.
My dd is also at the stage where 'boys are smelly' and so she doesn't want to play/share with the older one. If he tries to play she gets annoyed and will start being 'alpha' and then they'll argue in a "he said" "she said" manner. They never fight, but it feels like they need 'refereeing' and they spat. It is usually my dd starting it.
I want to say this is mostly normal, but I think it probably isn't? How do I deal with the situation?
