I think the answer lies in your baby. Her growth rate seems pretty normal. Is she happy and content? You've got to love that long stretch over night.
There are just some general parameters that guide health professionals dealing with babies. They don't apply to all babies - babies haven't read the rule books. When a baby follows a bit of a different path, it's just worth having a close look to make sure all is well. If you then conclude it "aint broke" there's no need to fix it. But most babies do feed according to the ABa information - and on the other side of the coin many mothers feel that their baby is not normal if it feeds 8-12 times per day. It is!
Just as a guide, babies usually lose around 10% of their birthweight in the first days after birth (yours lost less) and then regain their birthweight by 2 weeks, then put on 150-250g therafter for the first 12 weeks. They usually have one longish sleep in 24 hours. And one time of the day when they are grumpy and unsettled and want a cluster of feeds. And otherwise, they are just babies - sometimes they sleep, sometimes they don't, sometimes they cry for no reason, sometimes they don't
Have you considered joining the Australian Breastfeeding Association and getting along to their meetings? It's great to get out and mix with other mums and babies - see that they come in all shapes and sizes and with all temperaments and they are all....normal. And there are always breastfeeding counsellors available to chat over any issues you are having
