How do you get over baby fever 😔

My husband got a vasectomy after our second son was born. My son was a preemie 27 weeks and I had a traumatic labor with him and my son was in nicu for almost 4 months. I am 26 he is 29. I also have a daughter who is 3 and I got pregnant with my son when my daughter was only 5 months old. So 2 pregnancies back to back me and my husband had a talk how we do not want anymore babies and how hard it was for me. So we had a talk about the vasectomy and I said that’s fine just go do it. Cause I knew in my heart I couldn’t handle having another pregnancy after that situation with my son. Months later I started having baby fever just by seeing them everywhere and how before I wanted 3 kids instead of 2 but stuff happens. My sister is pregnant right now and most of the times I do miss having my baby bump that feeling of holding your baby for the 1st time ultrasound appointments were so excited for me but that’s no more I am thankful for my 2 babies but sometimes it’s just hard 💔😔
