My baby started to use both mother goose and DWE since she was born. She is now 13 months. She loves the songs in both sets. I think it's difficult to compare since the $$$ are very much different. Taking into account the price factor, I consider the CDs and books of Mother Goose are quite good. I personally don't like their VCDs and haven't let me baby have a look due to its poor quality. My baby moved her body and clapped her hands while listening to the songs and reading the books. For DWE, I believe that it is also a very effective tool to teach the children English. But the price is . My set was very very cheap as it was a second hand one got from my friend. My baby and I love DWE also. For English Time, I saw their demo before but I though it was a bit too difficult for babies and I didn't like their characters which was a bit ugly in my view.
