How about
Sparkabilities?
I haven't bought them yet, but after watching the four clips on their channel
http://www.youtube.com/user/sparkabilities (2 for babies and 2 for toddlers) my son showed me a shape in the clip and named it ("circle"). That's amazing considering he's non-English native and he does not like to name shapes in his own language! They are fast, entertaining and hold the child's attention. I need to save money to buy the four DVD pack because I believe that for my son it's worth it.
I like the way they teach music by using real musical instruments' sounds in the background, and the way they use a lot of stuff just in few minutes time. They have sign language too as I understand. It uses Doman method as far as I see and much more and some things similar to TweedleWink.
As a low budget family I found very useful to have these DVD's:
YBCR (the first teaching DVD series that we had and the first in our son's preferences)
Little Pim (we have Spanish)
TweedleWink (our son loves the affirmations and perfect pitch and sometimes vocabulary boosters)
Trebellina (the characters are funny and meaningful, our boy loves it)
Next on list ("next to buy" I mean, although they will be somewhere in the top of my list of preferences):
Sparkabilites - 4 DVD's
WinkToLearn Encyclopedic DVDs
I found about and chose all these with the help of BK forum members. The posts here helped me a lot.
The list above, next to LR and LM is to be used with our next child (whenever that is...). That's why I'm interested too in cost effective teaching products
Hope you find something that your baby will love!
