Hello everyone! I have a question for you, my daughter is 4 months old…

Hello everyone! I have a question for you, my daughter is 4 months old and I was giving her Aquadetrim 2 drops once a day. Yesterday I saw a pediatrician who said that she has a fontanelle closing and that D3 should not be given anymore. My masseuse who does massage on my daughter said that you don't give calcium but D3 and that I should give D3 from Aitherba and one time per day, 5 drops. Now I don't know what to do? The pediatrician I went to see, she has 30 years of experience, who should I believe? And do you give it or not? Please advise!
