Sometimes, she latches well for nursing and nurses long. As she winds down her eyes close and there are more pauses between rounds of sucking. And at the very end she suddenly picks up her vigour, sucking intensely and circling her head around, still hanging on tightly. Then in a final gesture she pops her head off and stops, holding the position: eyes closed, forehead and mouth pulled back, in a soft warm milky contented silence.
The best!
