I was given a bottle of this and am considering using it for my almost 3 week old but want to hear experiences and advice first. He's had horrible gas and has been so uncomfortable today that he's been up 7 hours with only napping for maybe 90 min total in 20-30 min spurts. It's not Colic because he doesn't really cry, just gets woken by it and fusses until I comfort him. He's also going through a growth spurt and cluster feeding a lot but I've been careful to burp every 5-10 min and keep him up right 15-20 min afterwards. Is he too little for it? Will it help or just make him more upset? Please any advice is appreciated!
