My baby girl is 9 month old... Doctor has suggested her to D3 Must 60K means cholecalciferol 60000 IU once weekly for 4 week. Is it safe for her to give such a high doses

A. seems to be a bit high itself luke you are saying. because our doctor suggested it once a month for adults and once in 2 months for 10 year olds. so for such a small baby once in a week sounds too much. better to clarify with your doctor itself once again and check as to why such high dose. or take a second opinion from another Pediatrician.
