Re: baby beingy fussy question/feeding
My guess is that it's just his tummy getting used to digesting and possibly a bit of overactive letdown/oversupply. If you feel your letdown is too forceful you could try letting the initial spray go into a cup/towel/burpcloth or nursing lying on your back with baby laying above you so it's flowing 'uphill.' I wouldn't do anything yet to try to 'fix' the oversupply, since it is so early and will most likely regulate itself. If the problem persists you might try some of the techniques to help adjust an oversupply, but at the moment I wouldn't worry too much.
