So my baby Tick opened his eyes A little over a week ago. He weighs about 99g and eating about 5-5 1/2 cc every 4 1/2- 5hrs (I'm slowly adjusting how much he eats as he gains weight so I don't over do it) . He eats great throughout the day but about midnight he takes about 2cc of formula and then he just wants to sleep the rest of the night but about say maybe 5:30-6am he's back to eating and then eats good the rest of the day. Just wanna make sure it's normal
