did you try giving some gripe water such as ‘little tummys’ which are usually all natural made of chamomile and other good safe things. that has helped us. also, always make sure to get a good burp after eating before sleeping
invest in a couple good soothing lullaby albums
we never felt the cry it out method was for us as we feel a baby should not be left to ‘self soothe’
the first couple months by us were intense, no sleep, bh it will get easier soon
