wow that's a high heart beat. not that I hold a huge amount of faith in the old speed of heart beat = sex of baby as my third boy had a 'girl' heart beat, but just thought it was worth a mention lol
also I had a late baby, then an early baby and number 3 decide to just be 3days late so that he could fit in the middle, and had spent the rest of his almost 3years doing everything in between the ages his brothers did lol
