I was pregnant for the first time and as a first time mother, you become too excited in buying baby stuff. The impulsive decision that I made during that time was buying all the baby stuff regardless if it's really useful or not as long as it is sold in the baby store. I made that decision impulsively out of excitement. When I gave birth to my baby, a lot of those things were not used at all, especially the clothes and it was a waste of money. If I had the decision to make all over again, I would carefully choose what things that are really needed so the rest of the money will be used to something more useful instead, such as milk and diapers.
Both options are technically grammatically correct, but the one that makes the most sense in this sentence is "when."
