my baby girl is almost 10 weeks now and in the last 24 hrs she's had some severe choking due to very thick mucus in her throat... ive been sucking it out, we just got a humidifier, and ive been in the bathroom running hot water to try and help... she seems content... but she does have a lot of excess mucus in her throat but no fever... im just wondering what might be causing this... is it possible that powder formula will? or is it a cold or something? ... i called her doc this morning and they said its normal this time of year, but as a new time mom - it scares me... what would help and whats causing it?
