Venting I guess?

I’m 29 weeks and 2 days with my first baby. My in-laws who have kids have been very generous by giving us a ton of hand-me-downs. Things like clothes and a few items that are larger, like a bassinet. I’m really appreciative of their generosity and all. But, my issue is the unsolicited parenting advice they offer up without me asking. Things such as, how long baby will be able to sleep in it, how long changing tables are useful for, until baby is more mobile, etc. I’m not unfamiliar with these things. I grew up in a pretty large family with a lot of little ones around, and am the oldest by eight years. While I understand the sentiment behind it, it does make me feel like they think I’m not knowledgeable or capable of knowing what to do/how to take care of my daughter...and she’s not even here yet. Am I too sensitive? It could just be the hormones talking, but this doesn’t feel helpful.
