Yes, my kids are expected to do "chores" with me. Even if they aren't exactly helpful at first, my oldest can now actually wash dishes and fold her clothes properly. She tidies up her toys and puts everything away. My son is... getting there. And even if they're not really doing the chore the right way, it at least allows me to get the housework done as they "help" instead of having them creating a mess elsewhere or demanding something. I also think it's a vital life skill to start early, and it helps them not take me for granted and it helps me not feel like a resentful maid to my children!
For me, going from one to 2 kids was BY FAR the hardest. It absolutely broke me. Part of that was my son's temperament; he was colicky and unsettled all the time. He's still a very fiery, passionate little guy but now (except for the tantrums haha) he's an absolute delight. Communication changed everything; when he started talking and understanding, our dynamic became a lot easier.
I am nervous about going to 4, especially cause I don't know how I'd handle another colicky baby (or a baby with medical needs, or something, I mean who knows what this baby will be like and of course my mind spins with the possibilities) and now I'm convincing myself that by writing it out I'm dooming myself to something... but of course it doesn't work that way.
How are you both feeling?
