my ds went to home based care (FDC) from about 7 months... i'd ask the following:
- how many babies do you have at any time, what ages etc?
- how do you manage routines of different babies at the same time
- how do you put baby to sleep (if you have a preference, i wanted my son rocked and def not just left in a c ot)
- what training they have
- who else is in the household
- who else visits the house
- pets
- any smokers in the house
- where would baby sleep
- where woudl baby play
- what 'activities' do they do
- do they go out - how
- what back up they provide
- flexibility with hours
- what cooling/heating they have
- why they went into this career
- ask to see some references or meet some parents
spend some time there and see how you feel
good luck!
