i found 1 - 2 hard for the first few months but then got used to being organised and that was fine. I found 2 - 3 fine until #3 got mobile and then it became really hard. There is 18 months between my first 2 (boys) and then 2 years between 2 and 3. Both #1 and #3 are very very challenging (#1 not so much now but for first 4 1/2 years he was a nightmare :-) ) so some days i think i should have stayed at 2, but then i wouldn't have my dd who i am so close too so i never actually regret it - just have "if id' stopped at 2 life would be so easy now" moments :-). 3 does bring extra challenges in the whole car thing - having 3 in car seats and finding cars big enough may be an issue. Also being outnumbered by kids meaning someone always has to 'share' mummy or daddy. I think if i knew what i knew now i would still go for 3 as my dd is more than worth it.
good luck with your decision making - it's such a personal thing only you can decide what's best for you and you will know in your heart what is right.
