Puck is not toooo bad, really. It is processed cheese spread, while cream cheese is not, but it's not as bad as Cheese Whiz for instance (which is the main processed cheese spread in North America).
Sodium is only slightly higher than philadelphia (110mg per ounce). If you can get Puck, it is made by the same company that makes Buko (the company is Arla) which is a nice cream cheese and has lots of good flavours that are fruity and your LO might like them better than plain - have you ever seen Buko?
