My LO is 4 weeks old and has been dealing with gas & been very fussy the past couple weeks. Her pediatrician said to not change her formula and just do bicycle legs to help her. I have tried gas drops that don't seem to help & the past couple days she has gone from eating 4 ounces down to 2 1/2 or 3 ounces every 3 hours while crying through the bottle. I just changed her to Enfamil gentlease since she was using Enfamil infant yesterday so I know it hasn't been a couple days yet but I'm not sure if anyone else has had the same problems and tried switching bottles. Right now I am using Dr. Browns..I will take anyone's help at this point! I can't keep watching my LO be uncomfortable! Thank you!!
