Picking a child to adopt: You are gonna want to pick a person who definitely wants kids or else you won't have as many kids. Also, you want to pick someone who only makes 15 a day. They will get you 690 in the end. If you can, this is very rare, find a person that is a carpenter or a builder. Don't worry if you don't get one now because there are other ways to get them.
Picking a spouse: You need a spouse who either definitely wants kids or someone who says that kids would be nice. Maybe is ok. Try to find someone who works in the same career room and has a job that makes only 15. If you can't do both then just pick one.
Stock up on food: It doesn't matter what kind of groceries you buy, just as long as you have over 2000 food stocked up. Some people say to just leave a meal out and don't let them clean it up. I try that all the time and it doesn't work. It only works if you pause your game when you leave which I find annoying because then no one grows at all. Each bag of food gives you 150 food no matter how much you pay for it.
Working: To make money, first start with the husband because if you play right then you should ALWAYS have a baby in the mother's arms. Take the husband and drag him to his working area. You have probably heard this before but praise him until he says Stop Nagging and then drag him back to the area. Repeat at least 20 times. When you are gone, he will make lots of money and get lots of promotions. Another thing you can do to help is buy all of the career room upgrades.
Kids room: To make an amazing kids room for around 3000 dollars for 6 kids max, first buy some children's beds. They sell for 550 at the shop. If they're on sale, definitely buy them. I bought bubble machines, balloons, a dreidel, stuffed animals, a toy ship, a giant teddy bear, a mini pool, and much more! This will keep you're kids extremely happy and never bored of their toys. You can use the same process on the kids that you use on your parents to make money. They'll never be mad or sad when you're gone.
How to give your kid good jobs: To make your kid a successful person, there are many ways to get them good jobs. If you want them to work in the kitchen when they grow up, then make sure they always play cook using the money method. To get them a job as a carpenter or builder, so they can build rooms for you for free, make sure they always play in the workshop using the praising and money method. That's what my 2 and 4 year olds have been doing most of their life. You can lock your kids in the workshop by putting a loveseat (99$) in front of the door (NOT A COUCH). I don't advise you to do that though because it sometimes glitches and they get out but can't get back in. You can lock in the parents too!
Selling collectibles: Most of you all know this trick, but to sell collectibles for more money, place 2 people on the collectible. You can't put the mom and the dad or they will try to have a baby. You can pause the game to do this if you'd like.
