So as many of you probably know, we've been having feeding problems lately. Luckily I have more milk now, expressing still isn't going to well but.

Anyway, my parents took Aurelia today for a few hours (they took her to church then to my stepdads parents house) and took with them the milk I was able to express over the week, about 3 o.z. maybe. She's 5 1/2 months and I've just started her on rice cereal, which she seemed to be enjoying, but now my parents have gone totally overboard with the solids and have been telling me I need to give her more! I've explained to them that really, she doesn't need anything but BM for the first six months but they don't agree. They started giving her watered-down juice a few weeks ago and even though I didn't agree, I figured it wouldn't do any harm (since they only use a splash of juice and its mostly water), and she seemed happier anyway to have the extra hydration.

Today when they took her out, they feed her the following things (much to my dismay)

1/2 a banana
a bit of PIKELET (which is like a pancake) with a smidgen of Jam!!
CAKE (its a healthy cake my stepdad makes but it has egg of course, and NUTS ffs)
MARZIPAN CAKE FILLING!! MARZIPAN OF ALL THINGS! sugar and NUTS anyone?

So I was completely flawed at this, obviously they didn't realize they weren't meant to give her these things, but then my mum was saying "She was so hungry! She was grabbing my hand when I was feeding her and shoving the spoon into her mouth! You really need to give her more solids, I think this is why she hasn't been sleeping at night."

Whatsit?
I mean, I thought at this age food was just to taste, not for nourishment? It also seems a bit hardkore for a new lil baby to have to digest all this food! If she was really hungry it was probably because she needed MILK, right?

I'm really puzzled here and don't know what to do.

Help?
