How do you get your sims to have kids when you have 2 sims that are married?

You buy a crib on infant and put it somewhere you can buy them with lifestyle points for like 5 4 or 6 or you could buy one for about 3,000 Simleons then you tap add baby (on the crib) and let the device do the rest it takes a bit of time and you will have to wait but when it has finished you can name you're sim baby you can pick it's gender and you can dress it to make it grow up you need to bake a birthday cake that takes a day and costs 5 lifestyle pionts so when it's finished then you can tap on the baby and tap happy birthday it will turn into a toddeler and do the same with the toddler and it will turn into a preteen

You should buy a bed from the infant section and put it in the two Sims' house. Then you can make a new sim

You have to buy a carb from the baby shop (when in shopping mode) the cheapst one cost about 3000 or 5000 sim money or you can buy them with LP but I suggest you get the 3000 one then do Cheats to get the money for it and do a cheat to get the baby to come asap one cheat you can do is
Go the the Sims make all your sims do a long action then cilck off and cilck the home button 2 times and hold down the sims freeplay and press the red - then go to settings and put it at any date in dec and go back to the sims you sud have more money and all the actions sud be done if this doesnt work put the date back and do it again but press the - after you set the date enjoy your baby
