Cally - wow that could practically be a new event at the Beijing Baby Olympics, competitive distance spewing! LOL! Like you I tend to let my babies suck longer before bed/at night - if they're in a deeper sleep it's easier to move them without them waking up too - also any sucking late at night boosts your supply more than daytime sucking because of a certain hormone peaking around midnight - so it's a good investment in your supply too! Kinda neat the way it works
