I would. It gets harder and harder to shop as you get further along and put together things like crib now because if you have to help get it together, that too is really hard to do as you are further along. I tried to put together this rocking bouncer when 9 months pregnant! Thought I was going to bust a gut! Well, you know what I mean . . . too uncomfortable at that point. Same for when I had to go to the baby stores to get things after my shower or return things. I'd try to have your shower around 30 weeks to avoid that. good luck
If your having a baby shower wait. But if not then go for it
