Just need to vent

So I'm 21 weeks pregnant and just need to vent.  I have a little sister who lied about her whole pregnancy( this is her first). She had a beautiful little girl! Now she trying to give me parenting advice!                                   I have two sons who our 6 and 4. We found out a week after she had her daughter we are expecting a little girl!  She tell me I should of had another boy because girls are to expensive! So she show up at are mom's house and hands me a garbage bag of clothes I tolder her thank you. I get them home and there so stained up i through the whole bag out. Then tell me I should have a baby shower because this isn't my first baby. To top it off she keeps telling me how to handle a newborn baby. She has also told me I shouldn't hold her daughter because I don't know how to handle a little girl.                                                     My mom wants to throught me a shower I said that was fine.  my sister is upset she didn't get one so now they want to do a shower for the both of us in November.( her daughter will be over 3 month old). It just frustrating to me!               Thank for letting me vent
