does she suck her thumb or have a dummy?
the gaps are good believe it or not, that means she will have room for her adult teeth to come through.
its worth getting her regular dental checks as that way you're in the system so to speak, early work can happen but is a very much an individual thing.
at this age there is nothing you can do

as a dental nurse im devastated that DD1's thumb sucking has created issues, she will need early intervention as well
