So DS is turning 5 on Monday and I have decided (last minute) to have 5 of his school friends over for a party. I decided 5 was a good number as he is turning 5, so one for every year lol.

I decided to have it at our house due to the weather being so unpredictable and raining on and off. Also due to being 36 weeks pregnant I thought not having to pack things up and take to it to a park would be easier.
The only things is it will be 5 boys and their parents in our medium/small house. If its pouring with rain the backyard is out also.

So what are some ideas to keep them entertained for around 1-1.5 hrs?

I have lots of puzzles, building/ construction sets, lego, playdough and colouring activities.

Would those be ok to do and would it keep 5 boys entertained?

Any ideas are welcome!
