Rather than buying, I'd recommend you join your local toy library. A years membership will be cheaper than buying 2-3 toys. I buy a few bigger quality pieces that involve open ended imaginative play (which is a bit old for 14 months) but otherwise I rarely buy toys. We have 'new' toys in the house every fortnight which means the kids never bored with toys they've already played with and mastered. Toy libraries are also great for the environment as they encourage recycling and generally have more expensive and educational toys that aren't found in Target etc.

At that age, anything that involves posting something, shape sorters or putting balls into something is great for their development.
