Hi doctor. My baby is currently 10 weeks old and was on nan 1 in his first week as i didn t have breast milk. He then started having silent reflux so we went to NAN AR. He has in the meanwhile developed colic as well. So currently he is on NAN AR and nexium for reflux and uses anti colic bottles from tommee tippee but its as if NAN AR is not filling him. He wakes sometimes every hour for feeds or every second hour. Someone told me to switch to nestle lactogen as it will fill him more.I bought it and saw its quite thinner than AR. My question- how will this fill him more than AR if it s thinner formula. Will it work for his colic and silent reflux in other words won t this thin formula interfere with his reflux and worsen it and cause more colic cramps and gassyness. He also poops once every 2 days and its dark green. Will he now poop less. What positive changes will I see in my baby when changing to lactogen?
