Re: 5-week old napping too long?
I would let him sleep at night and pump instead. Then develop a routine for the day that both you and he are comfortable with so he is eating well and you are able to avoid feeling uncomfortable. I personally do not wake babies at night to eat and have had great success with that. I do wake during the day to develop a routine. The fussy evenings is really, really common so I would go with whatever makes him comfortable.
