Occasional babysitter for three kids, to allow us to go out occasional

Looking for someone to mind our children on the odd occasion we get out. Have a few birthdays and weddings coming up to attend. Have a family wedding 15th August Babysitting would mostly be in the evening time so could entail giving meal (meal provided by us) or supper and doing bedtimes occasionally. I have a 6 year old girl heading into senior infants, a 4 and a half year old boy (5 in December) heading into junior infants and an almost 9 month old little lady. The kids have no allergies. Looking for someone with experience with minding multiple kids and with their age ranges and experiences to be confident doing bedtime routines.
