Good evening girls. We're two months old, we feed the baby every three hours seven times a day for 110 mg. We only eat formula. Who feeds or fed in our age? In the box of the formula it says that you need five times for 180 mg. He eats 110 and then spits up a little, is it worth changing the feeding regime? Very interesting your opinion.
