hi. if you type in 'mum and baby clubs malta' ul get some good info.
there is one in marsascala: [deleted], though i've never been to it myself.
there is also one in swatar, near mater dei hospital or the university. i think d sessions last year used to be held on thursday mornings between 10 and 12 or 10.30 and 12.30. it's usually a nice small group and i used to enjoy it. just type in 'mama knows malta' in your search engine and you'll get more info.
there's also one in swieqi / ta' l-ibragg. this is close enough to san gwann, (and not so close to marsascala). though distances are so short that i used to go to it myself, and i'm from zejtun, in the south, near marsascala. this one is held on tuesdays, i think between 10 and 12 or 10.30 and 12.30. it's right opposite the main church in ta' l-ibragg (swieqi, which is v close to st julians), so if you ask for directions you'll hopefully find it. it's quite a busy one and incredibly cheap, something like 20 euros for a whole year. if you go on tuesday, ul find it right opposite the church, and will see an open door with a gate to stop the kids getting out. you can just go in... if you go half an hour late after the groups started you'll see lots of kids and mothers inside.
otherwise there are the cana groups held in many localities. these specify that the child should b over 1 and a half years, though i think it depends on the actual group since the one i go to have children who are 1yr old. the other groups i mentioned above accept all young ages. also, the cana groups may be mainly maltese speaking depending on the area you join. i would imagine that in st julians and such areas it would also be mainly english speaking. the other groups mentioned above do speak english too, esp the ta' l-bragg/swieqi one which is actually practically completely english speaking. when you type in 'mum and baby clubs malta' in google search engine the first web site actually gives quite detailed info on the cana group child clubs in malta.
i hope this helps...
