I have a couple of fave things:

1. The swing that goes automatically if you turn it on. The only way to get a shower without worrying for many, many months!

2. Breastfeeding tops, especially the singlets. My gf that gave me those is forever in my debt! (To reward her I bought her the above swing when she had a baby, and she also agrees with me on its usefulness!).

3. ABA subscription. I gave this to 2 gfs and both appreciated it heaps. Comes with a great book on bfing that I have since leant out to other friends and has been worth its weight in gold. I didn't get around to joining until my bub was a few months old and would have loved it earlier.
