Tell me what you think

I put this in the introductions but maybe it didnt belong there?

Let me first give you alittle background info about my son, maybe it will help you, help me lol. Anyways I only breastfed for the first 2 weeks he was born, I just found it hard, it was like I was feeding him 24-7 and I had no time for my daughter. SO I stopped.. I started him on Enfilac. He seemed really gassy and I wasnt to sure if it was just the switch from the breast to a bottle. It lasted a week and I decided to change formula to Good Start. ANd he was fine for months. Well for the past 3 months Ive had problems. He started burping up more. He is 5 months now and it just seems to be getting worse. Its not just alittle burp up here and there its ALOT and alot of laundry to go with it! I dont even put him in his Bumbo chair cause that really gets the burp up flowing! He hasnt been a good eater. He moves around alot, like hes hungry then sucks alittle bit and turns his head. He grabs at the bottle to but I just thought that was him just messing around.The other day was bad, he burped up what looked his whole bottle and then clear burp up was coming up. He does a big burp up/throw up every day at least once. Littler burp ups are with every feeding and through out the day. Some of it isnt even after eatting and has become chunky ( sorry). He has started solids. Bananas seem not to agree to well and green beans are that great for him either.. Hes done good with carrots. I dont even carry him around facing me anymore cause he just burps up all the time. Does this sound normal or does it sound like there might be a problem?? He does have a dr’s appointment in afew weeks. should I wait and see or should I call the dr?/ I know I worry alot so maybe thats all it is.. Its just really upsetting when your baby cries, hes hungry and then he wont eat!! ANd then I feel like Im forcing him cause hes moving around so much.. Maybe I am forcing him and thats why he burps up.. HELP

Oh yeah one more thing, he does not cry all the time or anything like that..
