When my oldest some was born, we did not know the sex, and did not want to know. We thought he was going to be a girls and were quite shocked he was a boy. When my second son was born, it was a different story. We had a two and a half year old at home, and wanted to know if we should unpack, or go shopping. I think this is common with many first time parents. We did have to go home and get other clothes because the oldest was 8 lbs, 3 oz, and the second was 10 lbs, 13 oz, and two weeks early. We still had to go shopping because the size of our second child did not align with the sizes his older brother was in at the same season. I don't regret not knowing the sex of the first, or knowing the sex of the second. They may do the same.
