Yes - the Pickle (FF from 2 months) used to drain a bottle in approximately 10-15 mins. Nowadays it's more like 45 mins to an hour with some interesting positions thrown in - she currently favours an upside down sideways approach which I'm sure isn't great for digestion and certainly isn't good for my clothing which soaks up the dribbles beautifully. Still it does mean I have an excuse to sit down for an hour and watch a bit of sneaky TV (hhhhmmmm maybe that has something to do with the upside down sideways position??!!)
