DS is 5.5 months old and can't seem to get enough to eat. He normally eats 25-30 oz but now seems to want more which seems like a lot. He's waking up at night to eat too when he was sleeping through the night. He's not quite 6 months though and he was born early so I dunno.
Re: Did your LO have a 6 month growth spurt?
The general rule is 2-2.5 oz per pound per day. So an 18 lb baby would take in anywhere from 36-45 oz a day.
