Had two stillborn boys, both are buried together.  One was a cord accident, and the other was an underdeveloped heart.   They would have been our 2nd and 3rd child.  We ended up having another daughter after the fact.  Our plan was to have 3 children close in age, but evidently Gods plan was different as we have two daughters 4 years apart.  It was hard losing those two boys, especially when they were about a year apart.  But, I would imagine it would be tougher losing a 2 year old.  Would be more attached, and would actually get to know them while they were alive.
