What do you think about this?

I have two children already and I am planning to have another one before I am 30. I am 27 year old and have a diability but I am able to handle the children and in all. I be getting married soon. But that question. I got alot of money from Social security. I have to get it to spend down before 6 months. That till March. I was thinking to go ahead and buy some baby items. I was planning to buy bottles and so on. I'm going to wait on the crib and carseat and so on. Would it be ok to go on and get bottle and pacifiers. I don't think and the paicfer would be outdated. Thanks
