Can you please check these statements? Thank you.

1) My child likes throwing (tossing?) things into the air. He doesn't seem to bother with the consequences of his actions.
2) He spends most of his time playing with his Pokemon cards or with marbles.
3) In particular, he likes building tracks in the sands and used them to play marbles (?) with his friends.
4) He never wants to take a shower and he hates washing his hair. He doesn't like me to shampoo his hair.
5)In the morning he walks up to some rocks and then throws stones from them (into the river).
He challenges me to throw a stone the nearest to the other shore.
He never goes for a swim before 11 o'clock pm.

3) in the sand (unless there are different sands there!)

perhaps...and uses th em (since the main verab is Present Tense = he likes)

Child up swimming at 11 pm?!!
