The reason I drink, from time to time and in small amounts, during pregnancy has been explained above Msvee. I am really sorry about your family history and I could see that it would give you strong opinions. Given that, I would leave it there, but if you genuinely want to understand the other side:
I am not willing to live a significant chunk of my adult life (and, as I said, with bf-ing I'd be looking at around 7 years) where I have to avoid some things because for moral judgement reasons people have decided that they have to be proved safe before I do them, not that I will stop if they are proved risky.
Yes, you have to go to work. But you do a million things each day that you don't have to do. There are some that have known risks, but are still considered morally acceptable. Here are some examples:
- I crossed the road to buy some milk. We could have lived without it and had toast;
- I ran back up and down the stairs to fetch my wedding ring before going out. Unnecessary extra risky trip up and down the stairs at speed!
- I drove my car on a social outing. I could have stayed home.
There are also things I happily do because they are normal. On the assumptions made about alcohol, I should be waiting for a study to prove it's safe before I do any of these:
- I put on make up;
- I washed up with washing up liquid;
- I washed my face and body with various products;
- I put on deodorant
- I am sitting in a house with wifi.
But I don't, I do them, and if someone proves to me that I am risking my baby, well then I will stop. Just as I wouldn't drink a bottle of wine, because that is a risk. Just as I have stopped eating meat pate (which I love - there is a slightly more complex response on homemade vegetable or fish pate!).
It has naff all to do with relaxing, deserving it or being selfish. And everything to do with the fact that, if you are going to tell an adult to modify an otherwise perfectly health and responsible behaviour because of pregnancy or breastfeeding, you should have an actual reason greater than a moral high horse.
