Barcelona with 3 children

Hi There,

I am planning a move to Barcelona with my family sometime in the next few months. We are Australian and have been travelling for 14 months now. I have 3 children (ages 3, 6 & 9) who I want to find schooling, Childcare and activities for. The specifics of what I would like are:

For my 9 year old
Football (highest priority as this is his passion)
Swimming
Tennis
Martial Arts
Animation workshops
Piano
Drumming

For my 6 year old
Dance - classical/ modern/ tap
Swimming
Balls skills
Art (her passion)- drawing/ painting/ sculpture/ craft
Gymnastics
Piano
Guitar

For my 3 year old
Swimming
Playgroup with English speaking children
Music - singing/ dancing for 3 year olds
Daycare Protected content (not necessarily full days)

I would also like recommendations for good international (English speaking schools) that are preferably non- denominational and have a focus on pastoral care and developing a strong sense of self and place in a broader community with a creative and sports focus.

That should almost over it :-).

I wait in anticipation for a flurry of responses.

Many thanks,
Nicola
