Changing hours at work after baby


Have any of you requested to change the hours you work to something different? I currently am working 8am-5pm Mon to Fri.

I'm really wanting to change my hours after I get back from maternity leave to be 9am-4pm to lessen the time baby is at daycare.

For those who have done this, how did you go about bringing it up to your supervisor? Mine both have kids in daycare so I'm thinking it will be tough for them to allow me to change.
