I feel like people just throw around reflux and colic as a reason why the babies crying when in truth, babies do just cry sometimes for no apparent reason.
My youngest who's now 16 months has reflux, I know this because I was scrubbing lamb hotpot off my beige carpet and out my grout where he had projectile vomited it all up on Friday night! We can't give him water as he throes it up and we had to replace a 6 month old sofa when he was 8 months old because he destroyed it with sick!! I had to travel round pharmacy's in 3 different towns to get carobel as it was sold out everywhere at one time. I also slept upright with him on my chest as if you laid him down even at an angle, he would throw his feed up and cover himself and his bed in sick. Now that's reflux!
