Hi, I have started calcimax p (2.5ml * 2 times) and Depura vitamin D3 0.5ml for my 2 week old twins, since the last 4 days, as prescribed by their pediatrician. However, I have observed that their feed intake has reduced (they are on formula since I have lactation issues) and my daughter especially spits up/ vomits a lot post feed (sometimes equivalent to 5-10ml). I am very worried and hope to consult my pediatrician soon, but also thought to raise this here and get other parental views?
