my LO weighed 11lb2 last monday and apparently should b having 5oz bottles each day but he's barely finishing them...he tends to finish 1 or 2 bottles but the rest he only has 3oz-4oz sometimes less. i want him to start sleeping longer at night and hopefully sleep thro his 3am feed but i dont think he's eating enough during the day to do this. do you think it could b the formula i use? he gets trapped wind alot and i was wondering if this makes him feel full. He also screws his face up alot and spits his milk out loads...do think he doesn't like the formula? should i try switching to another brand and see if he prefers it? if so which brand? i currently use sma gold.
