I dont think there would be a problem. WHy do u think there is a reason u cant give it to her? I gave Omar cheese pastry, fruit tart, bites frm my pizza, & some homemade cake.
My LO loves quiche too but just be aware that sometimes the salt content can be really high
Ruby loves quiche. I make it, but find it a bit of a fiddle tbh

This is similar to what I do, although I make my own pastry, ready made seems to be fine too
