Hun, have you considered that it might be a growth spurt? There is a big one around 6 months. Has your LO previously been sleeping through the night? If not, then 1, even 2 NFs are still quite normal at this time. After nursing does she go right back to sleep? TBH, especially in the MOTN, I would feed if she went straight off to sleep. You could then work on spacing out day feeds.
At that time, I also fed twice in every A time for exactly the same reason as you - I thought she was waking in hunger from her naps. And she wanted it too -- she wouldn't go down for the pm nap without a top up sometime before. It worked fine for a while until BT feed started becoming a problem as she wasn't hungry enough. By then solids had also become better established, so I was able to space feeds out more. To my surprise, she took to it very well. Our routine (at 7 months) became
7 - BF
8 - porridge with breastmilk (2 oz at least) various fruits & dry fruits
after nap 1 - BF
immediately after - lunch
3/3.30 - BF
6/6.30 - BF
Between 10 & 11 - DF - which we have just weaned
I also started getting milk into her through the solids too, so with porridge, milk shakes, bread pudding etc. I simply use breast milk to cook for her.
