With four under 2 there are no spaces for other kids other than the one that is already in care and familiar since we are only allowed 5 kids. Under 2 is a misnomer too in the sense that the youngest will be 12-14 months when they start and by 18 months most are settled into daycare, walking, doing things for themselves so a child nearing 2 is really no different than a child over 2 but under 3.
