Without reviewing your court documents, the best answer I have for you is not to travel out of the US because having been convicted two crimes involving moral turpitude renders you inadmissible (not able to come in) when you return to the United States.
The question really is whether your crimes are crimes involving moral turpitude (CIMT). CIMT is not uniform throughout the country and certain crimes are CIMT in some places but not others. Right off the bat I think petit larceny is definitely CIMT because it involves stealing (dishonesty act). However, the endangering the welfare of a child is unclear. I think in some states/jurisdictions it's not a CIMT while in other places it could be a CIMT.
You should get your court documents from where you were convicted and sit down with an immigration lawyer in your jurisdiction to determine whether the crime of endangering a child is a CIMT in that jurisdiction.
