I prefer the under 5 crowd.
I used to despise taking infants but learned that I only felt that way when I had SA kids in care....they kept me so busy that I felt hurried/rushed while trying to care for the infants so I naturally assumed it was the neediness of the infants that was the issue....
...turns out it was the SA'ers.
Once I stopped taking SA kids, I learned to really enjoy the little ones.
Now however, I ONLY take infants of families I currently have in care. I find that by doing that, I already know the family and their parenting styles so integrating the infant into care is easy.
If I had my way....I'd serve the 2-5 crowd ONLY but that just isn't feasible where I am.
