It's seriously annoying both ds and myself! On a few occasions, it's taken nearly 15 mins to let down, by which time he's beside himself and there's me trying to keep calm and visulising everything from rivers of milk through to remembering those first feeds!
It's worse if I feed him overnight - he's starting to wake less overnight, down to just once every other night or so, but id also happening sometimes in the day.
I seem to have plenty of milk and once it starts letting down, ds has a really good feed.
He's eating really well and seems happy and settled in the day. I bf him about 4 times each day.
