It's up to you babe. With Darcy I had the fear factor and bought nothing...DH did but I didn't. I did religiously out money away every pay though.
With baby2 we were a looong time ttc and I started straight away. But sadly that bub passed at the start of the2nd tri, and so the fear came back.
Then came Nate...I was more cautious but not as bad as Darcy.
There ain't nothing wrong with a spot of window shopping though! Half the fun really!!
