I am a new mom and my baby boy is now five months old. After having him, I tried to breastfeed for about two weeks and he never would latch on correctly and I had a hard time using my pump while taking care of the baby alone (His father didn't have much time off from work to spend with us). Eventually,, I switched to Enfamil formula. He then started vomiting (Keep in mind, he was not "spitting up". He was VOMITING). He was on this formula for about one month and his pediatrician told me to switch to Soy formula, so I did. He was still vomiting on the soy formula at least once every day. The soy formula made him constipated so then I was advised by his pediatrician to put Karo Syrup in every bottle to ease the constipation, I did this as well. I informed his pediatrician about the vomiting AGAIN and was told to sit my son up for at least 15 mins after each feeding for reflux precautions. I just recently took him to the pediatrician because he sounded congested. His Dr told me that he could be vomiting because he is getting choked up on the mucus. So now his chest is clear and is no longer congested, but is still vomiting. He is also still constipated even with using Karo syrup in EVERY bottle. So, I took him back to the Dr and was told that he could be vomiting because he is constipated. I was advised to give my baby 2 prune juice bottles every day. I have been doing this for two days now and he has had a dirty diaper but has also thrown up.Several friends have told me that he may have reflux and may need a prescription medication to treat it. Like I mentioned earlier, I am a new mom and I have no idea what to do at this point. All advice and suggestions are greatly appreciated!!!
