My living room is generally clutter free - because I have teenagers now who are in their rooms or on screens or hanging out with friends. I do feel nostalgic for some of the toys, like the dolls house with all the tiny furniture! I loved that.
OP the toy phase is not for ever. I like a tidy house, but I also wanted my children to feel relaxed in their own home.
My solution was toy boxes / baskets (children’s toys should be robust enough to survive being put in a toy box, if they aren’t then they are not good quality, or not age appropriate).
I had a load of IKEA boxes for different types of toys eg a cars box, a dolly box, a train box, a basket for dolls house stuff, a food/kitchen box, an animals box, a musical instruments box, a dressing-up box etc.
We’d get out a few boxes each day, but not ALL the toys. That way it was easier to tidy as we would just chuck things into the right box, and they would get less bored of the toys, as they would be rotated. I would get them to do some token tidying so they had helped and I would quickly do the rest.
I can’t believe it takes you 2 hours to tidy a night - that’s crazy! I guess if you are putting everything exactly back - but be honest, does it really matter if a slice of toy pizza goes missing for a while under the sofa or bottom of the toy box? Are the children really bothered, does it honestly affect their play - or is it you that’s bothered?
And if they are asking for a specific toy that’s lost then that’s a good opportunity to get them to help tidy up and look for it. They learn consequences of actions.
But children should be allowed to play with toys freely in different ways, just because a toy is designed to be played with in a specific way doesn’t mean they will use it like that. Observe any nursery and by the end of the day the toys are usually mixed up!
Do you think your son is picking up on your stress about things being tidy and in the right places, and that’s why he’s so resistant to doing it? If he thinks he’s going to get it ‘wrong’ and has to find all the pieces or mummy won’t be happy, he is much less likely to want to do it.
But please relax and try to accept this is how kids of this age are, and it does not last. Think about other peoples’ houses you have visited on play dates. Which did you all enjoy visiting the most? (Both you and kids). The tidy one? Or the relaxed one?
