I've been waiting for my 4 year old DS to start swimming lessons and two different sessions have a place available for his age, Friday at 4:15 and Saturday at 10:15, I don't work on Fridays so would be fine to bring him and have something to do every afternoon but then Saturdays might be handy as he won't be in school that day but then we always seem to get invited to birthday parties on Saturday mornings. What do you think?
