I just needs clear 'rules' for her and for me.
Yes, I get that, I'm a rules girl too. What do you want to do, Anna? You know her best. I definitely wouldn't feed her at 10, unless you want to do a DF, which you don't.
I feel like its just clearer and more consistent to say no feeds rather than 'sometimes'.
I get this too. That's while I've always waited until I'm sure they can make it through, as it's not always clear. So, I'm very cautious, because once I did this with C, she dropped on the curve for a good while and while a lot of it is contributed to moving all over the place and not taking much to solids til later, I've always wondered if I should have held onto that NF for longer. I'm not saying this to make you question yourself, because yours is a different situation. Just wanted to let you know where I'm coming from, so maybe I'll just wait and let others chime in.
Also at 5-5.30 she's not ravenous.
Is this after being fed at midnight, or after going most of the night? If it's after going most of the night, and that's what suits you best, then I'd stick to your plan and keep pushing her through.
