DD2 is 4.5 months and has been around 75th centile for weight since birth. I've been in the habit if feeding roughly every 2-2.5 hours, on demand, but wondered whether I could get away with pushing it to 3 hours or do I still need to feed on demand at this age? I still demand fed DD1 at this age but she'd been born on the 50th and dropped to below the 25th.
