I generally follow the rule "if it ain't broke don't fix it". If you're happy to continue feeding at night and DS is happy, there's no real reason to change anything. He's still fairly little. I still bf DD at night, but at around 6 months when we started solids I noticed she began to drop feeds.
TC & LimeSlice - thanks I agree with that rule. I suppose I just started to question our night feeds after sitting with them for an hour listening to how well their babies sleep.

sloane - I think that's a long time to go without a bf too, I'd be worried about dehydration.

Kim - hats off to you for the hourly night feeds, well done.

Thank you everyone, I think I'm just going to keep doing it our way. It's working
