M.B.
One thing to remember.... I know others have posted it, also.. but YOU are very important... it is very important that YOU stay well and not so stressed... you are carrying 2 babies... you don't want anything to jeopardize their well-being at this point, also.
The hospital will take VERY good care of your daughter.. and I'm sure she understands that you can't be there every minute. Be sure to let grandma and grandpa help out in any way, either by helping take care of the other kiddos, or by helping with your daughter.
The DVD's are a good idea, as are any books she might like to read.
Let the school know what is going on, and ask for any work she can do once she comes home... that will help so she doesn't get so far behind. Be sure to get a note from the doctor saying WHAT activities she can participate in once she goes back to school, and also when she SHOULD go back to school. Give that to the school (make a copy for yourself, also, for your records.)
