Simply put, the answer is “no”. The reason we can say that, is because the institution of the Lord’s Supper is very clear in the means in which it is administered.To ask questions about in-utero communion falls under philosophy and speculation, neither of which have any biblical basis.
As you and your wife go to the table, I suggest you do so with the hope and the promises being made for you in the Lord’s Supper. I also invite you to go in the hope and the joy that the Word being proclaimed is also for that baby, as he or she awaits Baptism and his or her proper reception of the Lord’s Supper.
In His service and in yours,
