my son is 2 months 1 week old, 14.5 pounds 60.5cm tall, drinking 5匙平奶粉 too, but the doctor didn't say too much or too little... nor did she say anything about too heavy... I guess ok gwa.... don't worry!
my baby 2.5 months. usually take 180ml every 4 hours. 5 meal per day.
my baby takes 240ml this afternoon for 1 meal, then 120ml next meal, then return to 180ml tonight. So you don't need to worry too much ga.
