More kids or no?

Really struggling with the thought of if I want more kids or not. My husband was 50/50 with the idea till he had the last 5 days off with me an the kiddos an he got to see what I go through on the daily and he didn’t handle the daily tantrums l/ crying ( doesn’t help they both caught a viral infection) we have. 2.5 year old boy an almost 7 month old girl. I’m a stay at home mom. We own a 4bedroom home (so we technically have space for one more with our them having to share rooms) We’re both 23 years old. I’m not sure if I want another child or not at the moment because were wanting one of us to get fixed if we are done and birth control has not been kind to my body. Ladies how did you know you were absolutely done? Families of 4 are you guys complete? Seriously struggling 😭 (added to note: all my deliveries have been c sections so anymore children would be another surgery)
