I have had difficulties finding new games to play with D my 8 month old son, I looked everywhere online and asked around and someone suggested playing in water but I used my imagination and took it further to make it even more interesting.
So you get a wide shallow bowl around 3-4 inches deep and at least 10 inches wide and fill it nearly to the top with water ( I used tepid water so it wasn't cold for him). I then found a few small objects that float i.e wooden building blocks, bath toys or you could go natural and use blades of grass, flowers etc and put them in the water for bub to get out and splash around with.

I then added something else: vegetable dyes, they're great to add a couple of drops in as bub plays, D tries to grab the colour and has fun mixing it around, you can buy the dyes from grocery stores for around $3 for 4 colours and you can use so many different things with them as you can also mix them with water and flour to make a non toxic paint for bub.

(please supervise baby at all times when playing with water)
So there you go, if your stuck for ideas give this a go. Also if you have any games you would like to share please don't hesitate to share below.
