Yep. All of mine have asked to start breastfeeding again, once the next baby has come along. My 2 year old at the moment is very curious and would love to try feeding again. When I express he wants to 'help' and he has tried to steal the EBM out of the fridge on a number of occaisions in the past 2 weeks. Since I don't want them to re-establish breastfeeding (one at a time is time consuming enough for me), I just tell them 'no, that milk is only for babies'.
