Hi Loveitglows -
(Great username, by the way!) And a great question - we'd love to help.
Our answer may be a little bit different than you are expecting, but I want to share with you what we have seen with children who reverse their pronouns. We have noticed that speaking with correct pronouns is a skill that most often takes care of itself, when we help a child to have a better attention span. It is common for typical children to mix pronouns when they are first learning to speak, and they correct their pronouns as they observe people speaking around them. For our children, it's the same - when they are more connected and paying more attention to the world around them, they seem to correct their pronouns on their own.
So, my first suggestion would be to work on your daughter's level of connection. What is her average attention span? Could you help her increase this? And how much does she fully participate in games (physically, verbally, with real joy and excitement for the game, etc.). If you try to teach pronouns, it can actually be very confusing for both of you - trying to explain that you means I and when and why... Instead, help your daughter continue to increase her level of connection, and you'll see that she'll improve her pronouns most likely all by herself.
If your daughter is fully connected and already full through Stage 3 of the Son-Rise Program Developmental Model,then you can incorporate some techniques to help her with her pronouns. Let me know where she's at on the Developmental Model and we can give you more guidance if she's already done with Stages 1, 2 and 3. Otherwise, I think that the best thing you can do to help her with her pronouns is to help increase her attention span and level of participation and excitement for the game.
Also, be sure to celebrate any time when your daughter does use her pronouns correctly! Let's encourage her when she's already using language that does make sense.
Looking forward to hearing more from you.
