I am a 33 year old mom to a 4 year old boy that my husband is the step father of. We recently found out that I am pregnant again, and we are very excited to have a child together! We have already shared the news with family, and everyone is over the moon with us, but his sister has been very doom and gloom about it. He is 37 and she is 36. She has young children of her own, so we were suprised and taken aback that she seemed to only want to tell us all the downsides that having another baby will bring. Although this will be his first biological child, he is already very involved with my son, and is very good with him. We are both on the same page with parenting and how we want our family to be structured; I am a SAHM, as my husband has a well paying job that allows this, and we are both more "traditional/old school" in our parenting. We are on the same page in almost 99.9% of managing our family life, and we feel very confident that we are more than ready for this new baby. Regardless of all this, my SIL has been a negative thorn in our side ever since we announced my pregnancy. She constantly tells my husband how he is going to lose his current "lifestyle" and never get it back. She tells my husband that regardless of our intentions to raise our children in a structured environment, that it is futile and we will never get a desired outcome. She essentially throws her own children under the bus and uses their misbehaviors, personalities, and challenges as a comparison to our experiences. She also hyperfixates on the importance of giving the kids alot of material possessions, and since we don't share the same intentions (we are not very materialistic), we are in for a suprise when our children are angry and bitter that we didn't spoil them financially. It seems that every time my husband happily shares with her, she tears down his ideas, feelings, and the way we are already living our lives.  Today, my husband said that we wouldn't mind watching the same kids movies over and over again, and that if we truly got bored, we don't mind just playing games on our phones while our children watched the movie. Her response was an immediate, "bulls***, you're going to be too busy cleaning and doing chores to even have time to do that, and I don't care what you say, it's annoying to watch the same stuff repeatedly". Yes, she said this to my husband. Like, no matter WHAT he tries to take in stride, be positive about, she seems to want to smack it down and make him feel foolish or out of touch. Has anyone else had experiences like this with their family members during their pregnancy? Why the negativity? Everyone else in our lives are very happy and excited for us.
