Girls, hi ? Who has babies on IV, do you give them water? We live in Cyprus, and here pediatricians don't even recognize anything. Not a drop for colic, not supplements, and even water they say don't breastfeed ? Well, on breastfeeding, there's 90% of water in milk. But in mixtures much more protein, and it's sweeter. Little one seems like she's always hungry... She can't stand the temporary interval. I think that sometimes she doesn't want to eat but just drink ??‍♀️ We're 15 days ?
