Personally unless like Jec I HAD to be doing it anyway because MY kids needed to be escorted back and forth to the school and having 'less kids' during the day was something I aspired for NO it would not be worth it too me!

A) I do not like being ruled by a 'clock' during the day ... school age care pick up and drop off times almost always result in the young children having their naps cut short because anyone having a morning nap has to be up and dressed and en route to the school for 8:30 am and in the pm same thing to be at the school for 3 pm let outs ~ tired grumpy children = more work!
B) Inclement weather and physical RISK to having to take your other children outside in weather ~ walking in the heat in fall or spring no big deal, walking in cold and show that has been plowed is not so bad but that is not the only issue there is thunderstorms, ICE on the roads and well the fact that plowing is done inconsistent so some areas there is nice clean areas and others that are not shoveled and therefore uneven bumpy slipping tripping mess for young children ~ so if you are pushing or they are walking it is hazardous = more STRESS worrying about this
C) the larger the age range of children you have in your program the more challenging it gets to program for them ~ not that it CANT be done just that it is more WORK to provide it.
D) Having materials that span age group 0-12 will cost more $$ and take up more space in your home for storage of things to rotate or if you do not have that space than you have to make do with the 'same' materials and equipment which means more WORK at keeping kids of that age range engaged.
E) Finally before and after school children take up a space in your program in Ontario ~ however parents do not want to pay more than $10-15 a day for the service because from their point of view they are in school 'most' of the day and only getting a few hours of care so their fees should be reduced 'accordingly' but from MY point of view I would loose money offering this service cause a space is a space and why would I want to loose money doing something that costs me more $, more stress and more WORK???

Honestly unless ALL your children were school age and you were going to do this as a niche service so you could be 'off work' from 8:30 - 2:30 to do your own things with either your babe as a 'parental one on one leave' type or your housework and chores or another side business / hobby thing WHY would anyone want to have to work a 12 hour day tied to their home and clock and LOOSE money doing it????

The sad fact remains that care for this age group is in high demand because the service is not VALUED by parents in order to make it worthwhile for businesses to provide it ~ most parents would prefer to leave this age group at home as 'latch key kids' than to INVEST in the fees it would cost to ensure that they could find suitable care .... programs in the school boards have HUGE waiting lists for this service ~ WHY?

The schools have the SPACE to offer it so there should be no issue in opening up more rooms if there is such a demand for this service ~ however challenge is they cannot find enough employees to staff B&A programs staff turnover in the ones that are out there is constant because most people aspire for FULL TIME hours not some nasty split ass shift where you are working 3 hours first thing in the morning and 3 hours at the end of the day with 6 free hours in the middle where you do not have time to get too much done cause you are being ruled by that clock to get 'back' to work!

In Ontario the 'school boards' were being pressured to provide seamless days for Kindergarten / School age children if the 'demand warranted' it .... when they did their math to figure out how to offer this service, paying employees a wage that would ATTRACT/RETAIN people to want to do it and meeting the Union contract obligations the cost to parents was going to be over $35 a day for a normal school day and parents would still have to find PD / March and Summer care .... and basically that is just administration / staff wages and so forth because school boards already HAVE the space that is being heated/cooled/light basically 24 hours a day, they have the toys and materials and equipment and so forth .... and parents despite the demand for this service all BALKED at the reality of these fees and did not sign up for the programs ~ therefore school boards claimed to the Province that they do not need to offer the service cause there is 'no demand' for it

Society has to open its eyes and realize that this is a PREMIUM service because no one wants to OFFER IT ... so either pay MORE for it instead of less or continue to have your children be latch key children watching themselves before and after school!
