12 week old feeding frequently

[Jin]

Is anyone elses 12 week old still feeding .very 2 hours day and night? Sometimes she feeds for 40 minutes then wants feeding 2 hrs later from when we started. I'm told she should be going longer between feeds by now. Yesterday she wanted feeding all day and night. I'm guessing this was a growth spurt but the two hourly feeds has been going on for ages. I'm close to throwing in the towel and switching to formula except she won't go to sleep without the comfort of the boob. She has a few problems and the boob sooths her within 2 seconds which is why I'm still going.
