Childcare Needed

Would prefer someone calm under pressure who is able to handle care for two infants. Ideally late mornings to early afternoon hours for at least 4hrs/day 4 days per week, additional hours may be available from time to time. Boy/Girl twins born in February are on the same feeding and nap schedules. They are usually awake for 1. 5-2hrs at a time and nap for 30 to 60 minutes at a time, most days. Would love a nanny who can engage with the babies during wake windows doing things like tummy time, engaging in play or supervising activity center/mat playtime.
