First baby. 😊 16 weeks tomorrow. Due Feb 27th 2017.

This is my first baby, and I'm truly having so much fun watching the progress. I was wondering when you guys started buying stuff? I have days where I feel like it's too early, but then I have other days where I feel like time is moving so fast and I need to start shopping for this little guy or girl. When do you think is an appropriate time to start buying things for baby, aside from stocking up on diapers and wipes? Any advice helps. 😊
