My baby was a preterm baby (33 weeks 5 days) weighing 1.786kgs. Her lowest weight was 1.5kgs. Initially she was completely on formula / 30-60 ml pumped bf due to my low milk supply and her poor latching problems. Now with much efforts i have been able to shift her to bf+formula. She is currently 2months plus ( corrected age - 27 days) and weighs 3.5 kgs. Which formula is recommended for rapid weight gain?currently i am giving her similac advance 1.
