First-time mom or 6wo. Baby has starting gagging from time to time. Sometimes it's when she first attempts to latch on, and I assume she's just getting the nipple too far back in her mouth. But the last couple of days she's started just randomly gagging. Just an hour ago I had her in her bouncy seat so I could talk to her and play with her, and she gagged. Other times she will cough and almost sound like she's choking, again at random times and not while she's nursing. Should I be worried, or is there something I can do, or is this normal?
