Bubba T - glad your little man is OK. Dont feel guilty at all! I remember DD1 had ear infections like that too - and I too had just taken her swimming, didn't realise it was as bad as it was, but took her to the Dr the next day and when he took her temp it was 40! it hadn't been that high the night before. DD1 got them everytime she got a tooth - is your DS getting more teeth? fortunatley DD2 has been OK with the ears (touch wood). thought teething still puts her out of sorts - she only has 2!
good luck with your 2WW - I am just hanging out for Ov! DD1 going through night feeding again, and putting my cycles all out of whack!
