Has anyone gone for against their sensible head? How was it?
Practically speaking everything screams no.
My age (mid 30s but feeling old and tired), dc getting older and easier now, bedrooms, car, babysitters, attention divided between dc, days out, I don't really like the baby stage, detest the sleepless nights. Everything is made for a family of 4.
My heart says would one more really be so bad, if I could have a ready made 3 year old I'd do it. Just the love you feel for them. I can't honestly think of too many good reasons to have a third other than it might be lovely.
