Tip for taking care of 18 months kids

[Love&care]

Hi,

My 1st daycare is openning, haven't heard many calls. My age group is 2 - 5 years. Now I am thinking maybe I should change my age group to 1.5 - 5 years. i have experience working with 1 year old before and I have lot of experience wit 2.5 and up.

Just be safe, I need more tips on how to take care 1.5 to 2.5. What do i need to be aware of & can do with these age group. Any tips would be great appreciated. These are my questions:

1. How do you handle bathroom time
2. how often do you clean your toys, i can imagine they put toys in their mouth very often and common
3. how do you handle nap time
4. how do you manage for outdoor play, while you have some older kids?
5. Do i really need to buy high chairs and cribs for the little ones? what other furniture do i need to get?

Thanks in advance!
