Can I add egg yolks inside porridge and boil them tgt for my 8 months lo?

The whole egg is fine, from 6 months like all other food. Just make sure that the egg is cooked properly.

I would give hard boiled egg yolks for a start! Mash it and mix into the porridge

Yes if baby has no egg allergy. You can start with yolk and the white later on.

Np .. just need to taste for allergy. Is ok to test for egg white too

Yes if you have tested it and it showed no allergic reactions.

Egg yolks no problem. Egg white can't....

Yes if your LO has no egg allergy
