I used to play inside it even though there's no water. It's been my favourite 'play tent' since then, until Chik Chik disassembled it coz it's too bulky and eats up a lot of space in our house. Since then, I seldom play in it coz it takes some effort to blow it up again.
Anway, I do have some fun splashing in it at the pool. I don't remember when I actually go to the swimming pool to swim, but I guess it's around my 6th or 7th month. Coz mommy bought my swimming costume from Singapore when she goes there for training in mid June. I certainly have lotsa fun splashing away!
