I think it depends a lot on what sex you already have, and what you are having now.
I have a 6 ½ month old girl, and I am a 17 weeks pregnant with a BOY.
If I was having a girl. I would NOT register, and I would probably just have a ‘Diapers and Wipes’ shower.
But, seen as I am having a boy, and I don’t want him in everything PINK. I will register.
A new bumbo, bassinet, a bathtub, wash clothes, clothes, towels, high chair, bedding, etc. Are all things I would gear towards putting on my registry? The big items would more than likely be bought by family. But, I got a bumbo seat, bathtub, high chair, etc from close friends when I had my baby girl.
I plan on using my daughters’ carseat for the new baby, and getting a new cover for it.
People LOVE buying baby stuff. But, if you already have everything you need. Then I would not register. If you only need essentials….diapers, wipes, bath stuff, etc.
Then I would mention that ON the invitation….that way people know what to buy you. Like I said if I was having a girl I would not have a big old shower, and big old registry. My daughter is 6 months old!! Its all new stuff!
So, I guess it also depends on how far apart your kids are.
Main thing….if your registry would be usefull, use it. If not, mention on the invitation that diapers (sizes newborn, 1, and 2), wipes, and grooming equipment would be extremely helpful as we have everything else we need.
