Czech language exposure wanted for my children (Frisco, TX)

Hello!

I would like to find a native speaker willing to speak Czech with my children to keep their skills up, make corrections and help them with reading & writing. I would also like help with improving my own language skills. Perhaps there is someone who would like a PT nanny position, babysitter or something like that. I can be flexible with the arrangements and would just like to get the exposure for all of us. BTW, my husband is Czech, but travels frequently.
