Are all parents who struggled with infertility super competitive?

Or is it just my in laws? My husband and I had a baby a year before they did. They tried for 8 years and finally conceived. I thought the passive aggressive comments from my SIL would stop after they got pregnant, but it's morphed into this hyper competitiveness. Everything our child does, SIL has to make sure her child does it a younger age. We are into camping, kayaking, and gardening and mildly share them with our daughter. SIL is into none of those things, but now she is and so it her 18 month old and with gusto. Earlier this summer we mentioned we are going to get our child a fort or play area. Within a week she had one for her child who is too young for what they got. I mention that we should take our kids blueberry picking since my child had never been (she's 2.5). A week or two later, she goes alone with her baby I'm sure to say her baby went sooner than mine. Her baby was an early talker and mine was not. At first it was a little stressful for me (my dad was dying at the time I worried about my daughters speech and everything really). She pounced on that and was always talking about and showing off her daughters speech. I could never seem to escape the topic. My husband and I had been talking about getting a jeep for a while, now on their vacation they will renting a jeep, again, to say their baby was a jeep baby first. All of it goes on Facebook. That's why I got off. They are taking their baby everywhere so that they can show off how cool and fun they are on facebook (in reality they are very uptight and controlling).This stuff isn't a big deal to me, I've just noticed if I mention anything to her, my SIL is ON IT! I know a few other couples who struggled to conceive and they ALL are bound and determined to make sure you know their kids are better than yours and they are better parents than you. All of my other friends are fairly laid back parents who are all happy for each other successes. My question is for those who have seen this, how does this dynamic play out? How do children with parents (mothers) like this turn out? I worry for my daughter growing up with a toxic aunt. Thank you for reading! via /r/Parenting https://ift.tt/2DWCW2I
