Hmm not sure. How often do we use intials. I don't think I'd pick up on it but my mind tends not to notice things like that! Can you not choose a middle name to use in case it causes an issues down the line?
At work people often have to initial documents to show they've read them. Those initials would look like a comment! People on here might say it won't matter but might it matter to your dc in years to come? If you think there's a chance it will, which clearly you do otherwise you wouldn't be asking, then don't do it.
