AITA for not telling my in-laws about my pregnancy?

I (34F) have wanted to be a mom since I was 6. I came from a big family as the youngest, and I just love being able to see a child grow, watch them form relationships, and just have someone to spoil. I began working as an elementary school teacher in my twenties to help children, too.<br><br>My husband (36M) is the total opposite. He grew up with a mom, dad, and an older sister, and their family is small. He has told me since the beginning of our relationship that he doesn't want kids. He is just too focused on his career and doesn't feel ready to sacrifice his time and money. He's the opposite of me in that he doesn't even like kids.<br><br>We've been happily married for 5 years. I knew he was serious when he told me he didn't want kids, and I wasn't going to pressure him, but I shared with him my own dreams of becoming a mom. We came to a compromise: he would support me if I wanted to become a foster parent to children because it's more short-term than adopting a child.<br><br>I applied to become a foster parent, and I've had 2 kids placed with me so far. It's been a life-changing experience--truly the best thing that ever happened to me--and it made me realize that as much as I want to be a mom, I don't want to give birth to my own child. I would rather foster or adopt. My husband was surprised that I changed my mind, but he was okay with it because he knew how badly I wanted to be a mom.<br><br>So, my in-laws aren't big on the idea of me being a foster parent. They believe it's too stressful, both me and my husband should be more financially stable, etc. However, they do know that I've wanted to be a mom for a long time. They just wish it was in the traditional manner, as they believe that's less complicated and less stressful.<br><br>I'm currently pregnant (9 weeks). My husband and I went to a routine appointment with my OB yesterday, and we heard the heartbeat. We told my parents and my husband's sister. My husband made it very clear that he doesn't want his parents to know about the pregnancy until we're further along (around 4-5 months).<br><br>We've explained to his parents that there's a risk of miscarriage, and while it's too early to tell, I could miscarry. His parents agree, but they've shared that they want to spoil their soon-to-be grandchild. I also feel like they may begin to buy stuff for the baby, but that's just a guess. My husband and I don't want them to waste their time, money, and energy.<br><br>AITA for not telling them until we're further along? They are so excited to finally have a grandchild after years of waiting, and I don't want to deprive them of that. However, my husband is just worried that they'll find out later that I miscarried, and they'll feel disappointed.<br><br>Edit: I'm married to my husband, and we file our taxes jointly, and as of now, we can afford to have a child. We have enough room in our house. I'm also able to take maternity leave because I have enough sick days accumulated as a teacher. My husband is able to take time off too. My in-laws are not right in saying that we're not financially ready.<br><br>Please note that my husband and I have tried to use birth control, but it didn't work because I got pregnant. We tried to prevent this, but it didn't work.
