Tatiana, get someone to bed means to put kids to bed for the night.

get someone to sleep with you means to do something or otherwise convince someone that it's a good idea to have sex with you: [friend]: Why do you dye your hair blond every month. I think you look good with dark hair. [husband]: It's the only way I can get my wife to sleep with me!

[coworker]: So says you! Let's make a small wager: if I can get her to sleep with me by the end of the month, you'll owe me a steak dinner at Morton's. [worker]: You're on!
