My in-laws are coming to stay with me for a month and I am a little worried. I have my baby on a schedule - meals, baths, play, sleep. This allows me to work and have some quality time with my husband. However, my in-laws like my daughter to have a routine more aligned with theirs -- she should nap when they nap, then stay up late so that they can have more time with her. They are lovely people - but i really don't want her schedule to be upset. How can I speak with them about this?
