How do you fight the urge?

I’m so broody and have been since my son was a DAY OLD! How crazy does that sound?! I’ve got two beautiful boys, 3 year old and 6 month old. I’d love another I miss being pregnant I want my children close in age. But i don’t want more than 4 as I don’t think we would afford it so i don’t want to rush as I’m only 24. I just can’t stop thinking about it. I know I would get judged for being the ‘one with loads of kids’ because the people I grew up around are very ‘prim and proper’. Aaaand my husband doesn’t want another just yet. Don’t get me wrong i absolutely adore my two children I’m a stay at home mom and the love just makes me want more and more but that doesn’t mean I’m not enjoying them being young before anyone comments that. How do you wait a few more years because I’m struggling 👀
