Advise for getting the child to stop crying

[kindertime]

I wouldn't be doing anything like that for free. If she wants to sign up, let her. Maybe have a trial period of a week or two, but your time and effort are worth something and you should be paid for it.

As for how long you let him cry. You don't know this child well enough to know how normal this is for him. Some babies at 1 will cry all day. I had one like that. She cried the minute I moved 5ft away from her. Lasted several months. I wasn't about to carry her around all day, so it just went on. Whether you choose to put up with it, is up to you. But I don't think that you can judge from 1 hour.

If you think you would like to try with this family, do a trial period and then you both have the option to terminate if it's not working out. But definitely, you should be paid for your time!
