I have an 8 week old with colic who WAS feeding on demand every hour usually. The very nice HV convinced me he was getting overly full and it was aggravating his colic so since Tuesday I have been feeding only every 3 hours and for the most part he has not seemed to protest over that. Today he is especially fussy and I was worried he was going through a growth spurt and I should be feeding him more frequently. How can I tell? I dont want all our good work of getting to feeding only every 3 hours go to waste but I really dont want him feeling hungry for ages.
