My 27 weeker is finally home. His adjusted age is 49 weeks. He is on oxygen all the time at 1/8 of a liter because he has chronic lung disease. I am having a hard time keeping his nasal cannula on him. I have tried to adjust it time after time but somehow it doesn't stay in place. One problem is that he pulls it out a lot. I'm worried that he is going to pull it out at night or it is going to fall out at night when I am sleeping and he won't be getting any oxygen. Anyone else have this problem? How do you keep the oxygen cannula on your baby?
