They'll get most of their nutrition from breast milk or formula for the first year, so ideally prioritize bottles over solid food for now. We offered milk first about an hour or two before meals until she no longer wanted it. For instance, at 6 months when we started weaning our daughter was having milk at about 7am, 11am, 3pm and 7pm (and then during the night as well as needed). We didn't start off with 3 meals a day right away, but they were roughly 8am, 12pm and 5pm once we did. She eventually didn't want the 11am bottle, so I moved it to after lunch (about 1-2pm). Eventually because this was so close to her afternoon bottle, that one around 3pm moved later and started to decrease. Eventually she wasn't interested in it altogether and our day now looks more like milk at 7am, 3pm, and 7pm and meals at 8am, 12pm and 5pm, with morning and/or afternoon snacks as well most days. It just happens on its own, but I didn't see much change at all until about 9 months and she is now 14 months (and I don't expect her milk intake to reduce again anytime soon). Just give it time and let it happen. It will as they start to take in more food, but it's a gradual process.
