Normal and good (unless you are only feeding a few times a day!).
If:-
you are feeding to baby's cues,
you are giving baby at least 8-12 feeds a day,
baby isn't excessively sleepy (sleeping for more than one long stretch a day - 4hrs +, or difficult to rouse after a long sleep),
not removing baby after a set amount of time (letting baby rather than a clock decide when the feed is finished),
offering at least both sides per feed (doesn't matter if baby doesn't take the 2nd or 3rd, etc side just that you are offering it),
feeding is basically comfortable (start might be uncomfortable or even painful but so long as it gets better during the feed),
and baby is doing at least 6 wet disposable nappies or 8 cloth nappies a day
then you've cracked it! Well done 
If any of those things aren't happening, that can be worked on, it's not the end of bfing.
