Breastfeeding and colic
Some fussy or colicky babies are 'cured' when mom switches to a formula. This tells us that the infant was probably not getting enough to eat, usually because of low milk supply or a latching issue. Either issue can lead to a sort of 'frantic feeder' baby where extra gas is guzzled in. This can, of course, lead to colic symptoms.
There are lots of professionals who specialise in these problems and it may be worth seeing someone. In the meantime, here are a few videos about latching and feeding positions. This article has more on increasing milk supply.
