Apologies if I'm posting in the wrong place - this message isn't looking for advice!
My littl'un has been obsessed with this show since she was about 6 months old... She's now 15 months and we have a DVD of it that she watches to wind down before bed. My partner and I know every word of every song and I've often caught myself singing some of them in public, even when she's not with me!
DD is doing pretty well with her speech. She's just today started saying (well, probably copying me!) "How are you?" after saying "Hello", but for some reason she always refers to 3rd and Bird and/or Muffin as "Ding Ding"! lol I'm loving how she seems to learn something new every day.
