several nights ago i was putting evangelina down after her bottle, & in order to soothe her (& encourage her to stay down), i (daddy) was gently & rhythmically patting her bottom & lower back to let her i was beside her. after awhile i stopped, but continued to lay quietly beside her to see if she had already fallen asleep. without getting up, she turned to the side (to peek if i was still there), then reached back with her right hand & started patting her own butt with the same gentle rhythm!
