Hi, my 5 month old, who is only breastfed, has been trying to feed off of everything. It is different then her just putting things in her mouth. For the last couple days she has been sucking on my chin when I hold her, palm of my hand when I pick her up and my collar bone are. When have recently gone from 12 minutes feedings, every 2 hours, to 18-20 minutes, every 3 hours . Would LOVE to hear what you think ❤️
