We decided on two. When DS was born I was tossing up the idea of 3. DH was adamant on 2. After month 5 of TTC DD, I decided 2 would be it. I hate TTC. I hate being pg. I'm not a naturally maternal person. I love my kids to bits but I think had we not decided on two beforehand, I would have stopped at one as I really struggle on a day to day basis. I'm glad we didn't as I love my precious girl to bits. DH has now had a vasectomy so 2 is it. I'm very happy with that decision. Reasons for deciding on two were partly financial but mainly desire to not have an only child as even though I have siblings but a largish age gap so felt like an only child most of the time without the benefits of one-on-one parent time so very lonely. I wanted them close together for this reason. Had things gone my way they would have been only 20 months apart instead of 26.
