Hi Kyla,
I also love the website, maybe you can have just one bright colour as a background (the fuchsia pink on the first line would look great for example).
As a buyer, I'd have the following comments though:
1. whilst the lifestyle pictures show the babygro rom the back so you can see the cherry, flower design etc, when you actually click onto the collection pages, all customers will see at a first glance is the front of the babygro, so they will assume you don't have the other ones and will immediately click out... I know that the names of each product clearly say what the product is and that once you click into each product, you have another photo there, but the reality is that very few customers will actually read the title, and even fewer will click into each product to check just in case that is what they're looking for... you'd be really surprised as to how lazy (and stupid : ) ) some people are... So I think it might be better to put the back view photos on the collection page instead.
2. you only have a mobile number on the site. You can buy an 0845 number really cheap and then just forward all calls to your mobile.
Hope this helps.
Katie
