okay- take a deep breath...
1. if there is a high turnover rate at a Montessori school - that is a red flag..they are usually paid fairly well and take care of their employees...so there may be something there...
2. before you switch do a good review of who you want to change to. Ask questions about turnover, ask about schedules, routine, etc. get as much in writing as you can.
3. with gas prices the way they are - i don't blame you for wanting to switch...
4. if you stress, she will stress. if you freak, she will freak...let her help you make the decision to move - yes, she's only 2 - however, she can still verbalize to you what she wants...take her the place you are considering - with a HAPPY SMILE and EXCITED and see how she reacts...
