My kids just seem to hate each other most days, and I'm probably really sensitive about all the fighting. I know kids fight but I hate hearing it, and the whinging afterwards, and they just seem to do it deliberately to make the other ones suffer. I grew up with an older sister who made my life hell most of the time and I didn't want that for my own children, but it seems they do it and it makes my heart ache that I can't stop it.
But when they wake you up at 5am with their fighting over a stupid toy, and you've had a late night because of gall bladder issues or a toddler who wants to get up and play - its the absolute worst way to wake up in the morning and I just want them to leave me alone lol
