4yo Ds's best friend is coming for tea tomorrow for first time. She's Jewish and I know she is observant and eats a Kosher diet. So DS's favourite meal of sausages is obviously out (he told me this himself)! I was going to serve fishfingers, potatoes and veg with fruit and ice cream. Then maybe some cake for a snack when she gets here. I think that is absolutely fine but just wanted to double check. Can you let me know if there is anything wrong with that, or that i need to consider as well? Thank you!
