Remember: she may not parent (or grandparent) the same as you — and that is totally OK! Some in-laws may be strict, and others may be more lenient than you are used to. They may want to let their grandchildren stay up a bit later than usual when they watch them on the weekends or like to take them out for ice cream during the middle of the day. As long as it is not against your beliefs or causing any serious harm, have some flexibility.
