Hazel's tired

For some reason, Hazel is really fatigued and struggling to finish her feeds. We called the pediatrician and he's concerned. We just need to watch her closely now. We really hope she's not coming down with something, We do NOT want to end up back in the hospital! We think she just needs a little extra O2 to give her her energy back, so that's what we've given her today and it's definitely helping, We just don't know what caused the fatigue. Please pray for her - that she stays healthy and starts eating better without needing O2 24/7.
