Pregnant with #3 news..

We are expecting #3, this was definitely planned and no surprise ! My parents are very judgemental and will not be happy for us.. they have made multiple comments about not having another.. any one in the same boat? And recommendations on how to tell them ? I am very quiet and do not usually speak my mind, confrontations really bother me. Any advice appreciated !

I have already decided I am going to wait until 20 weeks.
