My baby is about to complete 3mths on 21st with mix feeding which is 10mins breast feeding and later formula. Problem is she was taking formula feeding upto 60ml and sometimes 75 to 90ml since few days she is taking less of formula which is less than 60ml breast feeding also she takes minimum 5 to 10mins but she is passing urine and potty on a regular basis. Is there something to worry if she has gas or acid reflux as she is doing well and not cranky for rest of day
