Unwanted projections upon my baby

I have no control over what associations others have with my child. For example, strangers have often said he is 'serious' when he won't smile at them, an attribution to his character and personality that hasn't actually formed yet, being put there My mom has said "oh its the first time in a while (sashiburi) that he is in a good mood!" which is not only untrue, but creates a story that he is a bad tempered baby.

My mothers case is one of her remembering what she wants to remember. The strangers case is a case of trying to feel better for not receiving a smile from a baby. Both create a story about a child who has no way of defending himself or the way he is perceived (yet).

I just hope that as he grows up, these projections won't become self fulfilling prophecies.

Like i said, i have no control over what associations people will come up with. Is there anything i can do to protect him from unwanted prophecies? I can counteract it by saying what i see. Building awareness in other people doesn't work because it just makes me seem defensive ("it is STANDARD for him to be in good humor! Its his default setting.") But i do see merit in counteracting the negative prophecies with positive characteristics.

On the second day of his birth, my doula asked me 'whats he like'? And i had no idea. Now 9 months later, i have a vague idea, but when i think of the solidity of a childs personality, i still really have no idea. Maybe when he's a child, i'll have no idea based on the difference from child to adulthood, what he'll be like as an adult. I think this unknowingness is a good thing, keeping me open to variation and not getting stuck in what i 'think' he's like. I know what he's like rihgt now. He's curious and occupying himslef with objects from my bag of baby toiletries and miscellaneous items. But what more can i know than what he is showing me at this very moment? All else is memory, and memory can fail, as shown by the example of my mothers memory of his moods.

Once again, a reminder to be present... now he's banging my deodarant together with his thermometer and laughing excitedly. And now he's twisting the deo-bottle from side to side, presumably exploring the weight discrepancy from the top and the bottom... but maybe just exercising his wrist. who knows.
