Cute site! I also like the logo with the bee sucking on a pacifier, especially since the website is catering to baby clothing. I think that you've done a fantastic job. The website is organized and neat, which is something I look for in a website.
Its a really cool site , Have you thought about adding facebook fan page on the home page that might good for your business. Also you may wanna make the Pay Pal payment acceptance display bigger and place it in the better visible place like a right hand side or the top.
Hi! Overall i like it very much. Opencart is a great CMS. I would like a few more pictures of the clothing in every article, to convince peole that you have good quality. Good luck.
