+1 gets easier. Colic sucks though, just methodically work your way through the different treatments until you find something that works for you or until it goes away anyway.
Possibly try to resist the temptation to keep feeding in dribs and drabs – new milk on top of partially digested milk in an unemptied stomach is one cause of colic.
Riding is possibly a bit ambitious, but make a point of getting out with the pram. Screaming never seems so bad outside, might help Jr to settle, and you’ll feel better for it.
The most annoying thing is that in a few months your brain will blank out these bits and make you think it’s a good idea to do it again!
