Then I realized it was the mixture of the different age groups.
When interests, abilities, attention spans and developmental approaches vary so much, the environment and the atmosphere itself is really tough to manage.
With that being said, any age group is fun and enjoyable.
Just so long as it's one age group at a time.
I have a very mixed age group (14mos, 2 2yo, 4yo, 5yo, 10 yo) full time, days can be challenging, Saturday's especially. They are awesome kids for the most part, baby sleep issues aside, so it's doable right now. If Only I could watch them in groups of littles, middles, or bigs.
