Hey Tan!!
I've just started Toby on 3 meals a day, cereal for brekky, fruit for lunch and vegies for dinner. And he has been sleeping thru as a result..
As before he was waking up once a night for a bottle, so I suppose he is a hungry baby!! And he eats anything we give him..

So maybe try some solids at night too and see if that helps her sleep babe..
But every bubba is different..

HTH and big hugs for u too..
