Are baby showers for 2nd babies tacky? In a word, YES. I also have to ask...
Wait, since when do DH's give a hoot about baby showers? Does he want to attend?
What the heck do you even need? If you're having the opposite sex this time and have nothing gender-specific for him/her, that's your fault for not planning well the first time. Do you have any relatives that you could take hand-me-downs from?
I, for one, hate showers of all kinds and would be Mortified if someone threw me another shower or even a sprinkle as I honestly don't need a thing and wouldn't even know what to ask for.
Ugh this topic just rubs me completely the wrong way. I don't even think I could attend a 2nd shower UNLESS it was for someone that had their first baby 10 or more years prior. That is the ONLY acceptable reason to have one.
