本来不想凑热闹但有点儿不吐不快

Your dear mom is not an outsider, she is an immediate(not extended) family member just like your hu*****and. You are a first time mom and you don't know how hard it is to take care of your newborn baby in the first couple of months or so. Your mom is here to help you and the baby and you will soon to find out you do really need it. Your mom is only here for a short time and it is the perfect time to introduce the person who rasied you and the culture backgroud you were coming from to your dear hu*****and. Just enjoy and appreciate your mom's presence and help, stop worrying about what you are worring. You and your hu*****and have lots of time to be intimate in the future.
