C.H.
All 3 out of 4 of my kids got constipated and I would put 1 tsp of dark KARO syrup in 1 bottle a day to help. The Dr said I could use 1 tsp per every 4oz but mine were good with just 1tsp a day. Also changed my formula to Gentalease Enfamil. 1 of my kids was real bad and I would mix an Oz of prune juice with each bottle until I got her regular then I continued with the KARO syrup bt did need the prune juice everynow and then. Also when you start food with your son Rice cereal, bananas and sweet potato would bind my kids up immediately so I used oatmeal cereal instead and if I did banana or sweet potato I would mix it with apples to balance it. (apples always gave my kids wet diapers). Worse case senerio you could use a glicerin suppository, used it twice on my son and within 5 minutes he went. You can get them over the counter at the drugstore in the kids section. Good Luck.
