I really like PeekabooBarn. my daughter is enthralled by it, and at 15 months, knows all the animals. Therein lies the problem. I want my child to know the correct pronunciation of the animals names. It's a rooster, not a "wooster." It's a pig, not a 'piiiiig." It's a horse, not a "hause." It's sheep, not "seep." and at the end, it's everyone, not "everone." I know it's cute, but it'll teach your child the wrong way to pronounce the animals names, and that isn't a good thing. On a side note, if you're trying to teach your child spanish, then it is an awesome app. All the animals names are pronounced without any inflection or "lisping." I hope they fix this. It is the only thing stopping me from trying their other apps.
***Update***
If you have a young child, this is almost a "must have" app. With the 3.0 update, there is an option for an adult pronunciation of the words. In my opinion, that is awesome. There are a couple more animals too. I have now downloaded Peek-a-boo Wild as well. The developers listen to what the customer wants and responds in a timely fashion. Thank you.
Version 4.0 will not install in my old iPhone (iOS 3.1.3) Essentally, I have lost the use of PeekabooBarn. Be carful if you have to redo your phone. You will lose a lot of apps.
