@ MarieCharlotte: Oh, it can happen to the best of us.
The painting was made about 1825. Poor Pauline was terrified when Stieler at first wanted to paint the baby naked as he had the idea to show mother and son as Maria and Jesus. She replied to him rather furiosly that motifs like that might be alright for catholics (the Wittelsbachs and Habsburgs) but certainly not for her as a protestant!
