Can a pharmacist be an refereee for 5 mths old baby

[z18runway]

I have 2 kids born in UK and Iam into filling MN1 form, My first child studying in school where their teachers ready to be as referees and they are happy to do for my second child who is 5 months old baby.

But the question is, the form states that the referees must be professionally engaged with the applicant, as my second one is 5 months old, will the teachers reference be accepted or can i ask a pharmacist as number 1 referee and number 2 referee as teacher?

(P.S)

I can contact Health visitor or GP , but they charge for it.

Either should be fine as the children are born in the UK.
