Nanny Needed For 2 Children In Houston

Hi there - we are looking for a sitter/nanny to help look after and play with our babies for 3 hours about 3 times a week. My wife is a stay at home mom and her mother lives with us as well. Our babies were born prematurely and we are looking for someone who can play with them to promote their development. We want to start with 3 times a week and depending on how it goes look to increase in the future. Ideally someone with a background in child development. We are slighty flexible with which 3 days and what time we get help on but are looking for someone who is consistenly avaialble.
