Disorganised to the max and I have a two year old.
My friend is storage. Out of sight, out of mind. I have a sideboard in the living room that holds nappies, wipes, nappy cream, hair brushes, clips, bobbles etc etc. Easy to bung the wipes in a drawer away from little hands that want to empty packets and easy to find when needed again. Same with after bath time. Everything needed is close to hand and is tidied away again in 5 seconds.
I bought a large fabric storage box that matches my living room colours, it sits behind the sofa and holds toys. Takes minutes to run around the living room and put all toys away rather than trips back and forth to her bedroom to put the million toys a day she takes out away.
I'm sure organised people are good at selling items that are no longer used. I'm not organised and I never will be so I toss them without any guilt. Clutter gets binned too. Bin, bin, bin.
Cleared the Christmas decorations away today and it's reduced my stress levels so much already.
Cleaning is easy when the house is tidy. Tidy is easy when there isn't "stuff" everywhere. There are points through the day when there is "stuff" everywhere but I know it all has a place to go and that makes it easier.
Nap time and bed time are when everything gets put away and something like harmony returns.
I get 6 hours a week when she is at nursery to deep clean properly and sort through toy storage to marry up pieces again. It makes the world of difference and only started in September but before that I felt I was drowning a bit and that was with a helpful DP.
It does get easier as they get older. The 10yo is pretty good at keeping things tidy now and I know we'll get there eventually with the 2yo.
