Are we supposed to enjoy it?
At the end of the day we are “supposed to” (by which we mean have evolved to do, and children need us to) love them, provide responsive care, provide physical and eye contact, take care of their basic needs and teach them about the world. We are not supposed to entertain them endlessly, play imaginative games with them, or centre our days around their pleasures. There is no pre industrialised society where this happens, and even in industrialised societies we have only considered it a parents job to entertain kids in the last 40 years or so.
Children are supposed to play with each other, which is why they love it so much. Playing with adults (other than some physical rough play with adult males) is a really poor substitute.
Some parents do like it, which is great, but for most of us we love and adore our children, but are at our happiest when they are happy playing with others or absorbed in discovering something new, and we are absorbed in our own tasks with other adults or alone, all together and around each other but not fixedly devoting our time and energy on keeping two kids happy.
My advice is that is you’re naturally a cave woman mum but you’re living in 2026. Spend as much time with other kids as you can so they can play and you can be with friends, (group holidays esp camping are the best) and wait until they grow up a bit. Revel in the lovely bits and tolerate the rest, it passes quickly.
