Has he hit the 4 month growth spurt already? We had a big uptick in night feeds at that age. Also that is the age when I started feeding her in the dark bedroom right on wake up from nap (well if she didn't wake up I would go in a do it as a dream feed!) because she was so distracted. We didnt start any ff until closer to 6 months, and I added them super slowly. The thing is that every time you top up with formula you are effectively signaling your body not to make milk at that time. I never did top ups, I just replaced a bf with a ff outright. What does the feeding routine look like now?
