My baby has always taken a good quantity of milk. Have just put her on "Hungry Milk" (in the past fortnight). She is currently on 4x8oz feeds a day (8am, midday, 4pm and 8pm) and she sleeps for almost 12 hours on a night. However the past few days she has wanted a lot more in her last 2 feeds - she has just taken a whopping 16oz on her 4pm feed. A record! Would be proud of her if I wasn't concerned she'd pop any minute... So - is this a growth spurt or a sign she's ready to wean. She's just over 16 weeks. HELP!
