Dd fell out with best friend....

.... And their parties are coming up. They have been friends since nursery and in first year of school. They are both v strong leaders and are spreading their wings. I just don't think my dd has been invited to her party. My dd still happy to invite her but I don't want any sniping. WWYD? I think I should I should invite her as they'll probably be best friends again given time.

I think your instinct to have your daughter invite her friend (ex friend/soon to be friend again) is right. So, are they about 6? Assuming about that from your mention of the first year of school. So if one shows up, the other probably won't even remember to hold a grudge.
