Hi, i have 3 month of baby boy.Before he burp after every feed and didn,t throw the milk, but now its a week that he has lot of gas problem in evening and in evening after 9 o,clock he throw all the milk what he drink. And about 11.45 to 12 midnight then he relax n fall to sleep.Health nurse also advise us to add formula which thick the milk, but after that he feel heaviness and this didn,t help.
