Coming here for advice

Coming here for advice cause Idk where else I can get it .. I want to add to my family so bad .. I have a 3 year old and a almost 8 month old and I wanna add to my family .. if I talked to my mom or other family members they tell me I dont need another kid .. but we can afford it and have a big enough house .. anyone else have kids this close together in age ? And wanting a 3rd?

Edit: to people commenting thank you ! A little back story I’m 24 I’ve had the same job since March 2018, my grandad past away in 2020 and after his funeral I went to his apartment to help my mom clean it out there was a envelope for my mom me and then my brother , I’m each envelope he had all 3 of us a note saying he had account for each of us that he put money in since I was born in 98’ and my brother in 01’ , I’m not gonna disclose the check amount but between his check and money I’ve saved since I was 17 I was able to get a three row seat suv and a nice 6bd 4 bath house I’m very great full to have what I have .. so my two daughters have there own room plus they have a playroom me and my husbands room and we have a guest room that my mom is currently staying in due to domestic violence issues with her husband and an empty room .. id really love to have another kid running around 😍🥰 if I had my choice and I’d love to have 6 or 7 kids running around I’ve always wanted a big family ❣️🥰❤️😍
