can you girls recommend me a bottle for my 4 month old. One that he can latch on to and feel similar to a nipple. I EBF and sometimes when i go out i dont like to breastfeed in public so i pump, but he doesnt like the bottle. Its hard for me because in order for him to eat i have to go back to the car and feed him there. ive tried Avent, Mam, Dr brown and it hasnt worked out.😕
