I can empathize Cocoon - I prefer to only have one 12 month old at a time ... the rest are older ... so for example my group is currently 11 months, 25 months, 3.5 years, 4.5 years x 2 and a 6 years old alternates with one of the 4.5 year olds.

When I was young and spry and worked in centres I could easily care for multiple infants - heck at certain times of the day you had 7 by yourself back than ... and they were WEE back than too between 17 weeks - 16 months ... only because back than the DNA in Ontario was not so clear about using 2/3 ratio during first two and last two hours of the day or over lunch not being available for THAT age group and our boss was applying it to it
