Confused, should i be worried..

JKR

FTM. LO is 5 months old and EBF. She weighs 7kgs. Petite. Generally happy baby.

Everywhere it says that fewer than 5-6 wet nappies a day could be a sign of dehydration.

And also, a nappy that stays dry for more than 3 hours could mean dehydration.

My question is:

What does 5-6 wet nappies a day mean exactly, as in does it mean 5-6 wet nappies that are wet and soaked enough to the point of it being time to change them (which would probably mean a pee every half hour or so)?

Or does it just mean nappies that aren't dry and have been peed in? Because my LO soaks up only about 3 nappies a day with just pee. She poops about 4-5 times a day on avg and i change her right away, but they're often just poop and nil or minimal pee. And only about 3-4 times a day, the nappies are also wet or only wet. I usually change her nappy every 4 hours anyway if there hasn't been a poop since the last change.

Also, depending upon the nappy i choose (pant style or taped style as well as the brand), the results vary, so am confused even more.

And about a nappy that stays dry for 3 hours being possible dehydration- does that mean NO pee at all for 3 hours or a minimally soaked nappy in 3 hours?

Someone please clarify.
