I’m starting to see this as a trend, although no doctors will tell me it is. My daughter is 2 years old and her levels have always been up and down and up and down. For a while, her levels were in the 0 range, 0.7 0.2 0.8 … all of a sudden she’d spike up to 8.2 within a week. We are still taking weekly levels and it’s just something you have to watch, make sure she has all her phe and keep taking the levels. Patience is key. We understand how u feel.
