Agree with the other ladies! You will be fine

I am the same as you, I like to take on older kids (18 months and up) but like everywhere, infant care is always the highest demand. I do admit I like to start the little ones during spring to fall as I find winter so much work to get them upstairs and downstairs and in their snow gear plus help all the others ones. I started off with a 8 and 10 month old and 2 two year olds and it was November. We stayed in a lot that winter as I just found it too difficult to get both non walking, non climbing children up the stairs. Come Spring, it was wonderful!!
