I knew a woman in Ecuador who brought her 10 (?) year old with her and she managed to work around his school hours without too much trouble I think.  A lot will depend on your individual child - how well does he/she integrate in new places and make friends?  What about medical conditions or reactions to vaccinations?  Is the child keen to travel and good at picking up languages?

I think you should at least give it a try!  I travelled to Spain with my son when he was young and he lived there with his dad when he was 14-15.  He got a place in school ok but I don't think he made all that many Spanish friends - however this is more down to his personality than anything else, he's a bit shy.  Apart from that everything was fine.

Technically I'm not a single mum, but my partner has almost no involvement in our daughter's life and all the responsibility of being a parent is mine and not his.

I'm probably in the same boat as you. I'm studying for the TEFL online so I can be with my baby and hope to get a part time job out of it, possibly with some private classes too. Childcare is the biggest issue for me as my daughter starts kindergarten next month, but if she gets sick, I'll have to be the one to look after her as my partner refuses to be flexible in any way and miss out on him going to work! Grrrr.

In the long term, I'm hoping that TEFL will prove to be a good long term family investment and if my partner continues to be absolutely useless, then at least it gives me some options for the future.

I'd be really interested to hear about other mum's experiences too....
