My L&M has just signed one of the DGD's up for a local dance class, it's 4 o'clock on a Friday, it starts next week.
So for the next 3 weeks it means collecting a DGC from school on Monday (DGD age 7 Gym club), Wednesday (DGS age 10 Pottery) and Friday (DGD age 4 Dance class).
Fortunately the pottery class is only on for 3 more weeks & Gym club finishes in July, so by September I will just be doing the lifts for one activity.
DGD who is 7 is starting swimming lessons when gym finishes & DD will be doing the bulk of the ferrying around for that.
The reason I do the lifts for the other activities is that my L&M arranged & paid for them & not always at a time that is convenient for DD.
