It's frequently up and down with tests and infections with very premature babies, Grandma60. Our little ones had some sort of injection, blood test, x-ray, lumbar puncture, examination and who knows what else practically every day for the first five or six weeks. When they came out of intensive care, we were on a high, then they were back in and out for a few days. On a few occasions, they weren't next to each other but in different rooms. What an emotional roller coaster! The doctors and nurses reassured us that this was the usual pattern for such tiny babies, and other mums and dads there had the same experiences. When they got past 3lbs and were starting to feed, they plateaued because they were using so much energy to feed, so they would feed then be topped up by tube to get more weight on them. It's all tiny steps but you'll look back and wonder when they were ever tiny in no time at all.
