In case it is because of the first version (although I have heard of people getting this trophy in that version) this is the list of updates that have come to the game since version 1.00.02:
Fixes in 1.00.02- Unleashed several dozen missing behaviors. Get ready to see your family doing some new stuff.
- Tutorial no longer blocks checking of email for office career peeps
- Fixed some breeding bugs
Highlights from 1.00.02 to 1.00.05:- Life event notifications were sometimes mixing up people's names when it coincided with someone going off to college. Fixed.
- People will sleep to a higher level of energy replenishment
- Adjustments made to offline food consumption, in-game hunger and eating. People will overeat less in game-off, and will never starve if there is food available. Expect to see slightly hungrier people when you turn on the game, and much more food in the fridge.
- Adjustments made to allow greater player influence on longevity
- Failsafe put in for refusal to breed
- Adjustments made to a couple of the more difficult trophies
- Working is a bit less tiring, other changes to energy usage and recovery
- Fix to prevent glove loss/corruption
- Emails-to-player now correctly reflect customized names
- New pet behaviors
- Pets no longer show up in store rotation once purchased
- Store rotation now every 4 hours instead of 8
- Story book shop item works now

It would be a good idea to contact the game vendor where you purchased the game to receive the update.
You will find the update information from LDW
here where Arthur explains how to update your game if you purchased it from LDW. This is also a crucial quote from that post in case you did not purchase it from LDW:
Note that we have delivered this version to all the other distributors (Big Fish Games, Real, Yahoo, etc), so if you bought the game at another game site, you should contact them for the status of the game update. If you bought your Virtual Families game from one of the other game distributors, DO NOT download and install the updated version from our site. Doing so will cause your game to revert to a demo, since other game site's activation methods will not work with our version of the game.
