If you had to choose between a third day of preschool or a gymnastics class for your 4 year old, which would you pick?

Some factors to consider:
1. Preschool does not have an outdoor playground, just an indoor playroom that they typically spend about 20 minutes in.
2. LO has the opportunity to attend a playgroup at his school every other week on the optional day.
3. LO2 could also do gymnastics but we can't afford it if LO1 does the extra day of school.
4. LO just misses the school cut-off so he has 2 years before starting K and will attend for a minimum of 3 days his last year.
