Thanks mom2boys. This is what I was pondering about the immersion programs in general. I would think at first it would give DD a challenge as she tackles the language barrier but once she gets past that the level they teach at would be the norm. And I fear that she would pick it up quickly.

One day while at a restaurant on a whim, I asked a passer by if she spoke Spanish and asked what the word is for head. From there I touched DD's head and said cabeza. I did that one time told her head and cabeza and she had it. We went on with the dinner not mentioning it again and when I went to put her in the carseat I accidentally bumped her head on the door frame to which I got the very quick response of "Ouch you hit my cabeza." Months later if I brought up where is your cabeza with her not hearing that word since she would quickly grab her head.

She also quickly learned her numbers and colors with no effort and this is in the English world so I would think she would have no problems when immersed in the language.

I do feel for you and your issue, because the big fear would be him losing the language since he hasn't been at it for very long. You could build on what he knows through summer programs and afterschool programs. I know a lot of them programs around here do both. It might be what we end up doing. I know we will be doing the summer program this year and if she really likes it we will look into afterschool programs.

I do know there is a French Immersion Montessori School here and I am going to look into that. But again thanks for your input. You really answered what I feared was the case.
