Moving forward things will drastically change for me since the new Ontario rules have kicked in meaning it isn't just sufficient to have a space opening it has to be for the correct age of child too. If it works out that I could take an infant at the required time I would allow the baby to have the spot provided the older child stayed in care 3 days a week. If the space is going to open way before they need care and aren't willing to pay full for the spot from that date then I would advertise to fill the spot of the older child for 2 months after due date (ie giving mom the 6 weeks recovery time she can use care as needed). No sense saving or wasting a spot on something that isnt' a possibility.
