When can i put cereal in my sons night bottle?

I need help guys my doctor said to give the baby rice for his last meal for the night bc he's not sleeping threw the night. She gave me some instruction but I'm still confused on how much milk he shoukd get for his last bottle

Do I really need a :

- Diaper genie

- wipe warmer

- bottle warmer

- lanolin nipple cream

- bottle sterilizer

My baby is still on the size bottles that you get in hospital because the tete on the tommee tippee bottles (and any other bottle) is too big for her... but i think I need to get her on the normal bottles now but is she still to small? She’s just over 6 pounds 🤔...

Or what is everyone else using to bottle feed baby at about that weight ?

Just looking for opinions from you ladies, about bottle making! I'm thinking first thing in the morning boiling the kettle and filling the bottles with 3oz of water, leaving them to cool then popping them in the fridge and adding the formula when needed then using the bottle warmer to heat up. Is this okay? Just I don't want to drive myself insane with making a bottle up every time it's needed..
