Not me personally, but my very good friend has had disapproval from her parents with every pregnancy too.
DD1 - Too young, still live in a flat
(they should have waited until they could afford at least a 3 bed house with garden apparently).
DD2 - Poor DD1, how unfair on her - how will you afford X school for two? (a local prep school, which was never on the cards for either DC anyway!).
DS1 - Where will he sleep? (Now in a 3 bed house with garden but obviously every child needs their own bedroom). How will you cope with 3? How can you afford 3? Poor DD2 being forced to be a middle child.
DD3 - Furious strop-off & silence for a month or so.
DS2 - Purely selfish. 5 children in a 3 bed house is akin to child abuse. SS will have them on "the list".
I should probably add that friend's DH works long hours & varying shifts but earns a very decent wage, so there is no financial reason to not have DCs. There is absolutely nothing going on that would be remotely of interest to SS - both parents cope brilliantly with 5 DCs (I wouldn't!) & they are a very happy, well cared for family.
Friend's parents decided to stop at 2 DCs themselves because they could "only afford" a 4 bed house and "everyone should have a room for guests". (Which is fine by the way, I am not criticising that choice at all).
This is similar to people who are put under pressure to give (or not give) their DCs certain names by their parents. They have had their turn at making a family & they got to make their decisions on numbers then. Now it's your turn, and your decision!
