You will most likely have a better acting child who feels the stability of having a set schedule to go somewhere. It will be easier in the long run.
Plus full time child care is often less expensive than part time. They charge you by the day and on that one day they have to have an extra teacher so it costs them more. If they have your child in the full time slot they have the same amount of teachers every day, they don't have to hire one that just comes in randomly.
That didn't say it right. When a child care center has a baby room they can usually have 4 baby's per teacher. If they have 8 baby's in there that means they have 2 teachers. If those baby's pay $30 per day times 8 baby's that is $240 per day that room pulls in. If the teachers are making $8 per hour the center pulls that out of that rooms budget, they've spend $128 out of that $240 for staffing costs. Then they have the cost of food for the oldest in the classroom. Even if they are spending $15 per day on staffing and food for that classroom they are making $90 for overhead costs and profit.
If they have 9 babies in that classroom one or two days per week they end up spending $64 times 3 for just staffing alone. Then they are feeding an extra teacher too. So they make a lot less money, about $44. That's not a lot to put towards the utility bills, insurance, cooks wages, directors wages, or even for profit to support your own family. So they charge that one person a bigger child care rate to offset the extra staffing and just plain out hassle.
The only way they can benefit and make this work and cheaper is to fill those other 2-3 days per week with another child to make 2 kids together one full time slot. That's why they really need a commitment and can't take a child on random days of the week. So they'll charge even more.
So if your baby is one of the original 8, they have a set schedule to be there and they hold a full time place your charge will usually be a lot less than a drop in type situation.
All in all, it will be easier on your child is they go to the same place the same time the same days of the week. This makes them happier and allows the center to have less stress and get to know your child better and bond with them.
