Should I use 'chats' logs' or chat's log'?

[Twilit1988]

My dear and respected teachers,

1 : "When we chat on Yahoo!,our chat's logs are recorded" correct?

2 : "I'll marry my son to that person's daughter" correc?

3 : "Put baby on his shoes" means 'make baby put on his shoes'?

4 : "I enjoy my studies" correct?
