###Human: Is something wrong with my 4-month-old daughter, or am I overreacting? ###Assistant: Hi , Choking like act, not laughing or crying well is something need a careful & detailed evaluation that she might be having delayed milestones and that can have multiple causes. If you can connect with me on video chat , I can have a look at your baby to confirm it is something to be of concern or not . Considering your baby is other wise normal with normal events during delivery & after delivery -- Small small amount of puking is normal which can be due to swallowing little more air during feeding. You Wrote - "while eating" , Just to re-confirm , have you started on solid food? Noisy breathing during feeds is due to running nose and she is having nose block so she feels difficulty while swallowing. Use Normal Saline nasal drops to keep the nose clean & open. Excess salivation at this age is normal for a well healthy baby .
