Should I be having another child??

My daughter who is the light of my life was born severely disabled with multiple rare conditions and is life limited to 2 years old (according to doctors it was a couple of days old to begin with) she is doing amazing and has hit every milestone so far. She is nearly a year old & I have been wanting to have another child for about the past 3 months.

Me and my partner have been discussing this and have been trying for 2 months. When I was 16 I was told that I would be unable to have children naturally so my daughter was a miracle.

After a 3 week stay in hospital I am now re thinking if it would be sensible to have another child when my daughter has extra needs.

Anyone been in the same position? Needing some advice!
