Quoting Holly Marie Read:" I do feed on demand. I've just been trying to have her up and have the lights on and get her active ... [snip!] ... I'm just glad to hear that maybe it's the people around me that are the weird ones and not me for wanting to go with the flow. "
Just keep doing what you're doing. As you'll get older her patterns and habits will get clearer and you'll be able to either set a schedule or continue to go with the flow.
My 7 month old has no schedule whatsoever. I had a rigid schedule with my first and while it was awesome to predict his needs, it was tough trying to plan my day around it. I have too much going on and not enough energy to concern myself with it this time around lol.
