You must first make them have a woo hooo to give her the perfect night, take her on the town for dinner and slow dancing. Wait until the baby is born then propose. she must say yes because u already have a child (or more!). SUCESS!
You need a female and a male sim that have romantic relationships. Keep on being romantic until it says "(sim name) finds (sim name) extremely irresistible. then under romantic you will see try for a baby. or you can click on the bed and select try for baby.
a month ur sim takes a month
I'm not really sure I think you can on The Sims Freeplay
the female proposes
There is no other way then speeding up time!
your sim can travel if they are pregnant, but they will not be able to give birth to a baby while on vacation.
If your sim is a male then yes, but if it's a female then no.
when two sims woohoo and you hear a chime then you know your sim is pregnant. also, if the two sims can "woohoo" but not "try for baby" then the female sim is already pregnant.
you get to a high relationship with the dog, and make sure it has a high relationship with the dog you want it to have puppies with (boolProp testingcheatsenabled true then drag up relationship bar, then go false). then make them have sex. SIMPLE
sometimes, u just get twins but u can have twins if u want to with this cheat (forcetwins)

I don't think there is because female Sims and male Sims have different clothing and it wouldn't work.
