When I started I got 2 wonderful kids, but after a couple of months an 11 month old enrolled and terrorized the others (pulling hair,hitting, etc). He was strong enough to try to fight the 2 year old! He cried a lot during the morning when mom left for a couple of hours. He was the first to come and the last to go home (from 7:00 to 6:00PM) and very often the mom will even pick up after business hours. During that time I was even considering to close, because I feel I wasn't good enough for this job. I am glad I did not. After a few months of hell they decided to leave and life was so much pleasant. It has been close to 6 years since and so much has changed. I can even go out during the whole morning out as a perk =)... Hang in there with the experience you will find what works best for you and your groups...
