saline drops are are safe to use,,use as oftn as required to thin out the mucus,,,,,keep the temp in your house from 70-75.not more or less is required.
make sure to keep your home well ventilated,,cross ventilatn during daytime, first part of day,atleast for 1hour or so..if you are leavng in cold region and opening window is not posble for you,,open the window like half way or half inch dpnding on cold weather conditions and put the fan onn,,(avoid keeping your child in this room when windows or fan are open or onn)
dont let your baby sleep in that room until the room comes to good temperature/normal temperature,,,
make sure your baby wears good sleeping clothes, that are comfortble and doesnt catch lint or dirt..
avoid using fragrances in the room where baby sleep...

for 21days old-1month old baby,,not much of cold remedies can be done except :

Thanks a lot Heatl!
I read both of the links given by you. Still wanted to clear the doubt as it was written that mostly babys have it from birth and my baby didn't have it from birth so wanted to clear the doubt.
I am just eating the ghee in panjiri and I am not eating any extra ghee...
When we tell others that baby is having congested nose everybody ( of course they mean it good) tells the remedies they know but I wanted to ask some person who really knows about it...thats yy I asked you...
Thanks alot for your help...

all your questions are solved in point no 10///the link that i gave....read that.seems you didnt read it.

there is diff between a traditional practice that a culture follows and it might have cured some % of cases,,but it doesnt mean it will cure all of them or it might even prove harmful to your baby. many a times, some of these practices are given the name of ayurvedic practice..because as to what i know ayurvedic drs never recomnd doing those things on infant :)
its only by word of mouth that its spread and sometimes it helps and sometimes it becomes serious. during my practice we have had patients,,one of them gave garlic oil drops to loose mucus,,wat you think baby reacted ?? nose got red, nasal passges got severe swelling..baby could resist crying at every breathe !
and the nasal spray that you are using is nothin but the salt water//sodium chloride water,,which is much lightr and better/safer to use thn something like castor oil or honey (sticky and might choke the baby)..
those practices are to be followd in presence of someone who has done it practiclly and knows it well how to do it carefully so that baby is not hurt or knows the worst effects if not done properly,,and not when you are alone...

1month age is too early to decide wther its cold or infant congestion....
and when it comes to stuffiness in nose,,most infnt get that,,the simplest reason to it is thr nasal passges arent mature..until now they were in your womb inside water,,they never had to breathe or make sure of those passges except gulping the amniotic fluid,,but now they are using it...9months in water and thn all of sudden out !!! infant nasal passges are just the rght candidate for open air, microscopic allergens to trigger mild congestion,,its quite normal until almost 3-4months.
even my baby had that and of all 14 babies i have taken care of in my family or outside family,,they too had them ! they outgrow that...just make sure from your side that its not converted to cold ! thats y i told to do above things.
about your eating ghee in panjiri etc does not effect the stuffiness. ghee is converted to fat and will give high fat hindmilk from your milk and not mucus ! as far as i know panjiri has many hot things too,,and to balance that we put lot of ghee in it...
so its balanced well ! you are not eating pot ful of ghee,,,are you ?

about nose full of mucus,,like i said before,,just make sure that watver congestn has occured with those lil allergens and nasal passges gettng matured,,is not cold..as far as the colour of mucus is of normal colour,,no worries,,if its diffrnt colour like darker or black,,it means he is gettng mild cold..
and spray the nasal spray,,it will loosen it and it will run out of nose on its own,,if not,,after a couple mins,if you use the nasal bulb,,it will not hurt baby and the mucus will come out without ne friction.you will come to know whther the frictn is occurng or not when you suck the mucus out... and if you feel a bit more spray is needed,,go ahead and try that...it will not harm baby,,thats for sure !
all this in goodwill thn trying somthng that is not approved medically ....atleast not when you dont have ne elder present who knows it well how to do, n all details.
its difficult to roll back when it comes babies health below 6months...as medicatns cant be given much and this the time he has to grow and not struggle with all these remedies...
so take care,,,if you feel that remedy will help your baby to avoid something that is natural to happen and is normal,,,,upto you..my work is done here !!!!!
good luck

Thanks a lot Hetal!
1. But how long can it persist?? will this go by itself??
2. When she was born she was not having this stuffiness. It started around 20days after her birth...is it because that she caught cold??
3. Some friend told me to give a drop of castor oil with honey and according to her it will remove the mucous through bowel.Is it possible?? Acc to her its a ayurvedic remedy. She also told me about SUHAGA( Borax)with honey..Have you any idea about it...???
4.I am eating Panjiri these days ...is Ghee in Panjiri having any effect on this stuffiness...I mean if its increasing the stuffiness...
5.Her nose is never full of mucous ..can I use the mucous ext bulb in that case too...will that remove the mucous then too...I am afraid of hurting the skin...Could you plzz advice me..
Thanks..
