Hi Aangeles,
Thank you very much for your tips. Do you think if my son only learn to read English from LR without speak to anyone in English is ok for him? I haven't put him to daycare because I'm staying at home mom. Probably will put him to the Daycare once a week next year to socialize with other kids. I really admire on you and your partner in guiding Ella to learn a lot of languages although both of you are working full time
