Hi daddy,
My son also had a protruding navel.
I don’t think it’s anything to worry about unless you feel a bulge beneath which could then be a hernia.
I found the information on this website useful:

However, if it’s worrying you, do get it checked by your PD. Am sure they’ll be able to provide better answers and solutions :)
Don’t worry too much tho :)
