Potty Training at Daycare

DD started potty training at home at the start of October and we dropped diapers two weeks ago at home and worked with her for 5 days.  She does pretty well at home, but her vocab is limited and she doesn't say she needs to go potty, just 'diaper' and looks nervous.  She will say yes if we ask her if she needs to go.  We have one or two accidents at most at home and have had several totally dry days.  At daycare they are taking her hourly and she pees everytime, but she still is having 3-4 accidents.  This is day 7 at daycare potty training.  Before that she refused to even pee on the potty at all at daycare so this is progress, but I feel bad that she's still wetting so often and worry that it will back track the progress we've made at home with keeping undies dry.  What do you think?
