So, DD is having 2 meals a day and has been on solids for almost 4 weeks now. I need ideas for what to give her!

For breakfast she has fruit (pear, watermelon, banana usually). Yesterday she also had some cucumber and a bit of toast with banana on it. She's tried some other fruits but these are her favorites and what we mostly have. Can she have citrus fruits? For some reason I thought she couldn't??

For dinner she has steamed veggies, usually three different types from these: beans, potato, sweet potato, carrot, pumpkin, cauliflower, broccoli, zucchini, peas.

What else can I give her? I feel like she'll be getting bored of this pretty soon. What can I put on toast? Also, when she goes to 3 meals a day what do I give her for lunch? And how do I know when she's ready for 3 meals??

TIA!
