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?

i understand your concern, but think about it - your in-laws want to do this as they really love your baby and want to spend as much time as possible with their grandkid. isn't that lovely? :) unless they are making your child sleep really late or causing too much exhaustion and disruption to her, i think you can let them take care of this for the time they are around - after all, it's only for a month. once they leave, you will need about two weeks to get your child back in routine.
