In my culture having a baby shower for every pregnancy is acceptable. We feel every child should be celebrated. My sister is expecting her second and I want to plan a baby shower for her and she is okay with it. However, we both married into families of a different culture than ours. So I don't know if I should invite my sister's inlaws and their extended family. I don't want to offend anyone or make them feel obligated to come. I guess the reason why I'm questioning this is because I recall my MIL receiving an invite to a sprinkle once and she thought it was ridiculous and was annoyed by it. So what do you think? Would you be offended and thinks it's tacky if you received an invite for a second baby shower?
