Am i a bad mom for not wanting another baby?

Hey, you absolutely have the right to feel like you are done having children! You know your body and health situation best, do what you feel is right, no one should make you feel guilty about it, I hope they are supportive of your decision once you discuss this with your partner 🫶

Why would not wanting another baby make you a bad mom?
I am an only and my life was fantastic growing up and as adult it’s even better lol what your MIL wants shouldn’t really affect your decision here. Your feelings might change over time but you shouldn’t pressure yourself into that. Maybe some conversations with your partner will help them to understand your perspective?

First and foremost: no, you are not a horrible mother. In fact, everything you just described points to a mother who is deeply devoted, fiercely loving, and carrying an incredible weight on her shoulders.
It is entirely normal and valid for reality to redefine what you thought you wanted. Choosing to prioritize your health, peace, and mental well-being so that you can be the best possible mother to the child you already have is not selfish—it is responsible and deeply caring.
Here are a few grounded perspectives on where you are right now:
1. You Are in the Deepest Part of the Trenches
The first 18 to 24 months of parenting—especially with a child experiencing sleep challenges, painful teething, and milestone delays—is pure survival mode. High anxiety, sleep deprivation, and constant worry consume an immense amount of bandwidth. Wishing for difficult phases to end doesn't mean you're wishing your daughter's childhood away; it means you are a human being reaching your natural limit

2. Nobody Else Gets a Vote on Your Mental Health
While your partner or family members may express a desire for more children or grandchildren, you are the one physically, mentally, and emotionally bearing the toll. You cannot pour from an empty cup. A child benefits far more from having a healthy, happy, emotionally present mother than from having a sibling.
3. "One and Done" Is a Whole, Complete Family
There is a massive cultural pressure to reach a specific family size or give a child a sibling. But having one child allows you to devote your energy, resources, and love to her without constantly splitting yourself into pieces. Single-child families are thriving, happy, and just as valid as families with three or four kids.
Thoughts on the Response You Received
The message provided to you offers one perspective, but it’s important to look at it through a balanced lens:
What is helpful in it: It rightly acknowledges that parenting without a strong support system is a daunting challenge

that "picture-perfect" families on social media are a myth, and that society rarely warns women about the true sacrifices of motherhood.
Where to take it with a grain of salt: The response leans heavily into the idea that "once you get used to routines, you may change your mind" and highlights the sibling bond as an essential protective measure. While that was their path, it does not have to be yours. You do not owe anyone a second child to prove your confidence as a mother or to fulfill an idealized view of family dynamics.
Will This Feeling Pass?
The acute, suffocating anxiety you feel right now will ease as your daughter grows older, becomes more independent, sleeps better, and navigates her milestones.
However, whether your decision to remain "one and done" changes down the road doesn't matter right now. You do not need to make a final, permanent decision for the rest of your life today. You only need to take care of yourself and your daughter right now.
Give yourself permission -

to pause the conversation about future children entirely. Focus on getting through the current developmental hurdles, protecting your mental health, and enjoying the quiet, beautiful moments with your baby girl. You are doing an incredible job.
Does having a firm timeline to re-evaluate (or officially close) the topic with your partner feel like it would take some weight off your shoulders right now?

U are not a bad mom at all. This is very real. I felt the same. U may feel differently after your kid gets older and I think waiting at least 2 years between pregnancies is wise to protect your health.

Your not a bad mom, if your one and done your one and done there’s no problem with that.
