It's not proper etiquette to EXPECT a second shower, especially if both babies are the same sex. However, if someone OFFERS to throw you one, there isn't anything wrong with that. If you truly don't need anything, your mom can always emphasize on the invitation that this is intended to be a nice gathering to congratulate the new mom and gifts aren't necessary. Or, maybe your mom can specify that gifts aren't necessary, but that there will be a sign-up sheet for babysitting your older child so you can have a little pampering time before the new baby arrives, or a sign-up sheet to bring meals after the new baby arrives, or perhaps accept donations to contribute to a spa gift certificate so you can have one last hurrah before the new baby comes :) . You may not need a lot of 'things' for the new baby, but, as a pregnant mom, you ALWAYS deserve to be pampered...even more so, since you're pregnant with a toddler to chase around this time! Several of my friends and I had our second children in the past 8 months or so, and we all ended up throwing second showers for each other and all got gifts for each other...not because the new mom NEEDED anything (most of us had babies who were the same sex as our first child), but just because we WANTED to get something for the new mom. Even though they aren't THAT far apart, I think it's always fun to go to a baby shower or get a gift for a new mom or a baby so, as long as you aren't the one actually ASKING for it, I don't think there's anything wrong with someone else wanting to do one for you. I have never been offended to be invited to a 'second' baby shower; it's just exciting to do something for a friend!
