Go through your child's closet and drawers. Pack away clothing that no longer fits or give the items away. Keep an empty box near the washer and dryer. As you do the laundry, place outgrown clothing in the box rather than hanging it back in the closet. Donate clothing you won't need again to a local thrift store.
Toddlers get presents.
But these events can result in an overabundance. Prioritize what your child can really use, then share your list with relatives. Let them know you appreciate their desire to give something to your child. Your list is simply a way to help guide their gift choices toward something your child will really enjoy. That's one of those pesky parenting issues that will emerge again and again.
