Back on Nasal prongs

I am 11 weeks old today.  I am the oldest baby in the NICU at Parklands Hospital...I am by far the smallest still though...I weigh 1,33kg today...my SpO2 has been quite low most of the morning...mommy and daddy think it is probably because the sister that looked after me last night had inserted the feeding tube into my right nostril - my good clear one...so I have been trying to breathe through my left blocked nostril...when the nurse removed the feeding tube a lot of mucus came out with it...mommy and daddy are upset...I have been struggling a bit and have been put back on oxygen for a while...Dr Egner said we must skip all bottle and breast feeds today rather...I also had physio started again today...a lot of sticky phlegm came out and was sent off for testing...my SpO2 has been going up and down most of the day...aunty Bridgitte is looking after me tonight - she was the first NICU sister I met on the day I was born...she let mommy cuddle me for the first time today...then she let daddy feed me with my feeding tube...
