I didn't know I was going to have number 3. I wanted to but DP always said no way. I fell pregnant and DP wasn't up for it at all. Said no way. But as i said to him at the time, I'm not asking you if we can, I'm telling you I am, baby is here, on it's way, it's happened. I asked him to look at his 2 DD's and asked him to imagine life without them and I then said it would be the same with number 3.
IMO, and it is only my opinion, you could regret not having this child for the rest of your life and wonder who she or he might be and what life would have been like. And you could never regret having a child and never ever be able to imagine what life would have been like without them.
My DD3 is now 4 months old. Life is fab, busy, but hey it was always gonne be. Her sisters adore her, we all do, she's such a lovely content little girl.
i'll go back to work 3 days a week and we'll get a slightly bigger house one day, meanwhile DD1 & 2 share a room.
It'll all all be ok, watever happens.
