Life Time Wish - Surrounded by Family! Tips :) How I did it.

With the Surrounded by Family lifetime wish, you need to raise 4 babies to teenagers! I wish I could tell you it's not that hard, but I'd be lying. It's a LOT of work, and you'll need to give up a lot temporarily to take care of the babies and toddlers.

Preparation
Now, the easiest way to get this done quickly is to either have triplets and then another baby (like I did) or by having two sets of twins. I prefer to just have triplets, because with only 1 space left in the household it guarantees that you'll have one more baby. I'll put a link here- - to explain how to get triplets. Since a Sim household can only have 6 Sims, you need to start off with a mom and dad - only two parents. Try for a baby and make sure you dedicate an entire room to the children. I had one of the cheapest houses in the game, so all I did was expand the walls to make more space. I would recommend you DON'T put the cribs in  the parents room because it will constantly wake up the parents (unless they both have the heavy sleeper trait.) Also make sure the parents get a high-quality bed - they'll need to get their rest! I also recommend that at least one of the parents quit their job so that you have time for them.

Babies!
A babysitter is fine when they're babies, but this way you can't really build a relationship with them at a young age. I kept the mother, River, at home at all times, and her husband, Blaine, was in the middle of the athletic career track and kept his job. I even hired a maid to clean the house every day (Cell Phone> Call for Services > Maid) because it really is time-consuming to take care of kids. It's only $125 a day, not too bad at all. On top of that, both my parents were Slobs. ^__^' This was much needed.With 2 or more babies, it's likely you'll need to get a parent to wake up in the middle of the night to satisfy their many needs. Like I said, you'll need to give up a few things. I had no time to work on my parents' skills, watch Tv, or even cook at times.

Toddlers!
When the babies are finally toddlers, you might think it gets much easier, right? Haha, nope. ): Have another baby right after they age, or another set of twins if you did it that way. Add another crib to the room, and buy around 3 toys to keep the toddlers entertained. (Doll House= +Social need; Peg Box= +Logic; Xylophone=+Guitar) The FIRST THING you need to do is potty train them, which doesn't take too long. You'll save a lot of time if you don't have to constantly change diapers, and the maid will empty the potty. After that, I started teaching them to talk and walk. I didn't do this all at once, I just did it whenever I had the time and they weren't sleeping. The parents sort of went into a cycle where the wife was basically nocturnal, and the husband could do his day job/ teach the toddlers in his free time.

It gets much, much easier to manage once they're all children, minus all the homework. The parents finally get some alone time (I swear River and Blaine did not speak to each other once while raising these brats.)

I did this in a very small house (y'know, one of those 15k houses with only one bathroom/bedroom). So don't think it's not possible, it's just crazy!! Good luck! :)
