This can be a very frustrating thing to do, and you may be tempted to give in and just do it yourself (as my hubby often is!), but try these ideas and hopefully they will make it easier for you!

Firstly start getting them to help as soon as

Make a game out of it - "see how fast you can put your blocks back in the box", race each other putting things away, see if they can fit everything back into the toy box so the lid closes, etc.

Turn their favourite music on and dance around with them while packing up - they will think this is great!

Explain why the toys have to be packed away and make them feel like a "big kid" for doing it.

These tips can also work with house work, my son loves to vacuum and dust. While I am cleaning the shower he wipes the cupboards and basin, while I'm vacuuming he takes over and when I'm folding nappies he tries so hard to help!

Just remember they may not do a fantastic job, praise them anyway - at least they have tried! Don't make any of this feel like a boring chore - make it all as much fun as you can - it will mae your life a whole lot easier!
