Other wide-mouthed bottles look like breasts, the unique LACCH dione nipple moves and works like breasts, helping to facilitate the baby's transmission from breast to lactation and back.
The LATCH nipple expands and moves and pumps, so the baby can breastfeed just like the breast.
The bottle also features a unique anti-dipping LATCH valve, which is a single-piece basic vent valve that prevents air bubbles from passing through milk, reducing the chance of cataract.
Just use the lactation nipple with this lactation.
