THIS ANSWER IS FOR SIMS 2 PC (it may not work for other editions)
the sim has to have an accessable bed for this action, make sure nothing is blocking it in any way ( except for a bed side table). click on the bed and select RELAX. your sim has to be a child or older, toddlers andd babies cannot relax! hope this helped! xx
click on bed and press relax
Get both sims to relax on a bed and select 'woohoo'.
Have them relax on the bed and click on try for baby.
Make sure you have a double bed... then make both sims "relax" on the bed then Click "Try for baby"
It depends how long you leave your Sim alone on the bed. Because Sims are known to act like real humans, when they are left alone on the bed they tend to relax and read a book. There is no actual number or prediction to how long Sims relax, it just matters how you control it. I hope this helped :)
If your Two sims are in Romance level (You know this if your sims can Make out) get both of your sims to relax in Bed by clicking on the bed and press Relax. Make sure both of your sims to do it. Then click on the sims you want to Woo Hoo with and press Woo Hoo or Try to have a Baby
in the sims 1 for the PS2 you can have a baby, have two sims make out few times or have them both relax in a bed and select "play in bed" if you have the sims 2 for the PS2 then you can't have kids.
If your partner lives in the house with you, simply select each sim and choose the relax button on the bed. If they do not live with you, select your sim and choose relax then click the other sim and select invite relax on bed.
you need to have two sims that are in love, then have them both relax in a double bed, and then select "woohoo"
You have 2 sims relax on a bed adn have them try for baby
Make sure both sims are in love, then get them to relax on a bed. Click on the Sim you aren't controlling, and select WooHoo.
all you have to do is if you live with them make one relax on the bed then switch person and get them to join them if they dont live together get them to marry and they will move in together
