Hi,

It's normal to wonder what's going on when their pattern changes, - but she is also behaving completely normally. It's an interesting exercise for adults to count how many times food or liquid goes into into their mouths. They tell us to have 8 glasses of water per day, 3 meals. A couple of snacks are normal. Already up to 13 feeds. Yet, strangely, a little baby, who needs to grow and who has a very little tummy is expected to get by on 4hrly feeds - just doesn't stack up.
Enjoy the longer night-time sleeps.
