baby shower registry

Teresa
So this is my first baby and my baby's father and I have basically nothing at all for the baby. We bought a bassinet and a crib (crib is still on back order and hasn't arrived yet) but with money being so tight these last few months, we haven't been able to put anything aside yet for our baby who is due in April. My mom is planning a baby shower and we were in charge of the guest list and we invited close to 100 people and my mom said that's way too many. My thought was that half these people won't come and I want to be sure we have a good turnout and a better chance at getting things we need for baby. We also have two registries, at target and babies r us with about 100 things on each and my boyfriend wants us to add walmart as a registry too. Do you think three registries might be overkill?
