My cousin is expecting her third child - her first child has autism, her DS2 doesn't. I was talking to my mum at the weekend and she bought up how my cousin's DS1 had a lot of issues and she thinks my cousin has been selfish in wanting another child - i.e. she won't have as much time for him when the new baby arrives.
I feel really upset at this statement because my DS1 also has autism (although he is very easy-going) and DH and I were planning on trying for another baby later this year (she doesn't know this). Now I feel silly and selfish for wanting another child and it has made me doubt our decision to try for another 

The irony is that my mum had a child with SEN and then went on to have me and my sister
