I think this may be one of my favourite breastfeeding paintings (Allegory of maternal love by Francesco de Mura). Mainly because as a Mum of many young boys I feel I can relate to the mother in the picture on every level. This is a scene I can well imagine in my own house:
'Mum! Mum! There's a bird in the house! It's going to peck me!'
'Well maybe it wouldn't peck you if you kept your pants on! I am trying to get your two little brothers into bed! I will deal with the bird in a moment!'
