It's a great idea. One of my favourite baby shower gifts was a practical one - baby hair brush & nail clippers. I knew I needed them and I hadn't managed to even look at them. Although the dresses & toys for my dd were cute I loved the practical gift.
BUT, the fact that my friend who gave me the practical gift apologised multiple times for giving something practical, took some of my joy out of getting the present. Don't apologise for giving a 'bad' present. Give it and smile - it's a great gift you've chosen!
