My daughter was only 6 weeks when she first went and only 6 lbs at the time. she was a premie. The girls in the infant center were so careful and never took there eyes off of her. She is now 8 months and she gets cranky if I have a long weekend and she doesn't get to go. She is so smiley when i drop her off and as a single mom, that's the best feeling in the world knowing that your pride and joy is being taken care of and is HAPPY every day.
