Speaking of language acquisition... September is coming and there are once again many opportunities for you and your children to learn or improve your Estonian.
TES Lasteaed - toddlers to age 7 - Saturday mornings
TES Täienduskool - ages 7 - 13
and teen / adult classes - Tuesday nights
TES Keskkool / Gümnaasium & Esto101/202 - ages 13 - 18 - Monday nights

All levels welcome those who have no prior skills in the Estonian language.

Thanks!
I would love to visit Mme MacDonald at Southwood Park P.S. and show her how wrong she was, but she's probably not there anymore. That was years ago! I hope they have better, more enlightened teachers there now.

Good for you, for standing up for the truth!
Multilingual people don't, in fact, confuse their languages. That convinces me that your child's French-immersion teacher doesn't really have a firm grasp of French. You should tell her that that the typical Estonian (in Estonia) moves comfortably among Estonian, Finnish, Russian and English.
Then, there are some, like Maxim de la Trine, who don't confuse languages for the simple reason that they can't speak anything at all.
