Can the toddlers wet themselves get taken away or die?

They can wet themselves but not die or get taken away.

I am using a ipad 2. If you want to get more money, you go on Sims and have all your sims planting beans. Then you x out of sims and double click the home button and hold down the sims app until you see the app wiggling and click the minus sign. Then go to settings>general>date and time and switch the set automatically from on to off and change the year to 2011. Then go back to sims. ( it won't work) then go back to settings and change the time from am to pm or vise versa and add a minute.
Ex. 4:20 am becomes 4:21 pm
Then go back to the game ( it won't work again). Then go back to settings and change the time again the same way.
Ex. 4:21pm becomes 4:22 am. Then go back to Sims and all of your sims will be done planting.

Don't think they can do either!

The parents can not care for the child anymore it is too much work can I give the baby to another one of my families?

No.

1)They do wet themselves. They leave a yellow puddle on the floor and start stinking (sometimes they stink before peeing due to bad hygiene). The brown smokes suggested they pooped their diaper. But even if they are wet, todddlers are still happy, unlike the baby who cries when it's wet and dirty.

2) They don't die. Their meter Bar does not go below 10%. Once all the bars are red, they will stay there, they will not empty.

3) They don't get taken away.

4) They don't cry, either. When their needs are low they might get angry (jumping up and down) but that's occassional, not all the time. If you let them loose around the house you will not even Notice their needs are low. Only when they are dirty.

But in general, you don't even need to look after your toddler. The worst that will happen is that it gets "housebound", meaning they will not leave the house until the needs are taken care of. But if you forget they exist, they will pee and poo, but nothing will happen to them. They don't die, they don't get taken away, they don't cry. They will still Dance to the radio if you put them to. Toddlers in Freeplay never lose their perkiness. Even their gait (unlike older Sims, who walk differently when they are not sparkling) remains the same at all times.

They can wet themselves like any other sim. They can be taken away/die in other Sims games (it's harder for them to die but it's not impossible) but not in The Sims FreePlay I don't think. Hope this helps!
