So everyone likes to send your kids things especially grandparents. So what might be a helpful way to get what you need and have room for is to send them a monthly list. Like we just ran out of bubbles so that would be a good thing to get. And Ila wants a baseball mitt. By making this list you save money by not having to buy everything they need and people can send you a sweet gift that you actually want and will use. A particular book or even bath towels. From my experience grandparents are happy to buy anything for their grand kids and it is even better if it is something they need or want.
So make a list and send it out once a month. With clothes (sizes) or books or toys you might need or want. That way they next time a care package comes you have one less thing to buy.
