I was in Sainsbury's earlier and I saw a woman pushing her trolley around with a boob dangling over and a baby of about 5/6 months sitting up in a trolley seat trying to crane it's neck and get a decent feed. Surely it would be easier and make more sense to just take the baby out of the trolley and feed it? I have walked around shops feeding DS before but I would always be holding him either in a sling or in my arms.
