Hi L.,
I would tell grandma that she can have 2-3 days a week with your daughter, but that she NEEDS to remain in daycare for multiple reasons.
The first is the whole change in routine issue. A child at 1 year old is very sensitive to changes in routine. To do that to her twice in 2 months is not good. You need to be thinking about the well-being of your daughter. Just because grandma wants to spend time with her does not mean that is the best thing for her.
The second is that her daycare is a school, not a babysitter. The whole time she is playing, she is learning. You know that grandma will be good with her, but grandma is no pre-school teacher. Point out all the things that your daughter can do, that she would not have been able to learn had she not gone to daycare.
And, finally, is logistics. If you remove your child from the daycare center, you might loose her spot. You would also, most likely, have to pay the registration fee again, and start all over (her spot would most likely be given up to someone on the waiting list). To make sure that she does not loose her spot, you would probably have to continue paying tuition. I don't know about you, but if I was paying +/- $100 a week, I would sure a heck want to send my child to school at least a couple of days a week. If grandma wants more time with your daughter, ask if your daycare would be open to grandma helping out in your daughter's room.
I hope you find this helpful. As you can tell, I have had to go through a similar situation.
Good luck.
