We have been trying for our rainbow baby for a year and a half (lost one Jan 2015@ 6wks and had a chemical pregnancy in August 2015). Finally, got my bfp this week. We had told our son about the Jan baby right away but didn't mention the August baby. We are planning to wait, hopefully for the baby to make it to the first trimester before sharing the news. Does this seem okay and how did you tell them? My son is 7yrs old and so wants to be a big brother.
