O2 at home

[LM96]

My little guy was born in Nov at 30 weeks (almost 31).  I received steroid shots at 26 weeks and they gave me one shot the night before he was born but did not have enough time to give me the 2nd one.  He was on O2 in the hospital for about 2 weeks until his PDA closed and then was on room air.  He came home at 35 weeks with no O2.

After he came home, he got exposed to plenty of colds courtesy of my older 2 kids (plus it was a very bad year for bugs around here according to our ped).  It seems that every cold he got, it affected his lungs worse.  Well, he just caught another cold (it's June--we aren't supposed to be sick right now!) and ended up on O2  for a few days.  Our choices were to either go to the hospital or do home O2---pretty easy choice IMO.  We are looking at using it 24 hours for a few days and hopefully on Monday we can go to using it just while he is sleeping (and in the car probably).

Anyway, a few of questions about it since unfortunately, I'm sure that there are mamas in this forum who have dealt with this.

First--are there any tricks to keeping the canula in his nose?  It seems to rotate out, especially when he is nursing.  He actually isn't pulling at it too much.

Second--what is the best way to remove the Tender Grips from his cheeks?  I know they don't need to be replaced very often, but we have played with the canula a bit too much trying to keep it in place and they are starting to lose their stickiness.

Lastly--how do you work it when your child only needs the O2 when sleeping?  Do you leave the Tender Grips on them when they are awake without the O2?
