Sensitive Gag Reflex? - Port Jefferson,NY

my son has always had a sensitive gag issue. it should get better his has but is not completely gone and he is now 7,for some it slowly gets better for others they are just sensitive that way,I also found out thought that he was tongue tied and so that just made things even more difficult for him. as far as the mucous goes young children are not able to get rid of mucous like we do,blow your nose etc. so all that drains down in the throat and just builds up and builds up until all that can do is throw it up,happens with all of them. milk I was told is not the best thing to be giving them to drink while trying to get hem well it just makes the mucous thicker. hope this helps and wish her a quick recovery.

If she's throwing up a lot, ease off on the milk and keep her on Pedialyte for awhile.
It helps balance her electrolytes.
Dairy can sometimes thicken mucus, so - no milk for awhile (2 weeks) till she settles down.
Besides Pedialyte, try soup broth, jello. maybe a little bit of yogurt.
Then banana, rice, applesauce and toast.
When you try her on milk again, go slow and have her sip small amounts at a time - never give her large amounts that she can gulp down all at once.
An irritated gut can stay irritated for awhile (sometimes 8 weeks), so try to be patient and don't panic.
Keep noting symptoms and checking in with her doctor.

When it comes to milk, only give her 1-2 ounces at a time. Then hold her upright for 15-20min. (She can even just sit upright on your lap.) Then give her another 1-2 ounces and sit her upright again. I know it takes a long time to finish the bottle this way, but it give her stomach a chance to calm down.

Some children do tend to throw up when they have a cough. It happens when excess phlegm is present and there is persistent cough. I know it is annoying-I KNOW. My son, when he get sick...he is so DRAMATIC with the coughing. Any little irritation and he is coughing and gagging and ultimately puking all over the place. Last year he had a cold and he was still taking a bottle at bedtime of chocolate milk-it was the only way he would go to sleep in a decent matter of time. So we were tired and we would give it to him-every night we would start coughing and 2-3 times a night he would puke on the bed. yucky-foamy-smelly-grossness. a lot of laundry and no sleep for mommy. Not to mention if he actually ate something during the day and started coughing-puke on the carpet.....it was lovely!
In addition, you mention the vomiting occurring after milk. Some people develop more mucous after drinking milk. I believe it is a milk allergy.
What we did was just stopped giving the milk before bed. and sometimes we wouldn't give it at all. If it is just going to come back up, why have the mess. I think you should call his pediatrician and explore that option.

My daughter was the exact same way and she outgrew it. She is almost 3 and I can't remember the last time this happened. I'd say she outgrew it about age 2 or a little older. I don't have any advice for you...we also worried and had to suffer through this with her. We had so many puke stains on our carpet we ended up ripping them all out and putting in laminate wood floors. She also woudl do it after a bottle, but not always. She would do it when sick, when upset and crying, when coughing. The doctor told us she would outgrow it and she did.
