With #1 we didn't find out but I new inside that she was a girl.#2 we found out and It was good preperation as we did'nt have any stuff at all for bub, We still brought some boys things just in case they got it wrong.
This time we chose to find out as we are getting two for the price of one so far they tell us one boy 99% sure whitch is great the other one was a bit shy at the scan but the lady thinks its a girl. Will look again at the next scan in another 9 days Before I start sorting clothes.
Finding out is a personal thing if your unsure mabye just wait for delivery day or do the envelope thing.
