Gap between DD's two top front teeth?

[CrazyLady]

Hi, as the title suggests my DD has a gap between her middle 2 top teeth. It's rather large at almost 3mm wide. Did anyone elses child have this? did it close when more teeth came through? Did it cause issues with other teeth coming through? If it didn't close did it cause speech issues (eg a lisp)?

I'm quite concerned because one of my teeth sits back and causes me to lisp. I'm VERY conscious of it and can usually get around it but will forget when I'm tired or not concentrating on my speech. I don't want DD to have one too

Thanks in advance!
