Mine is 4 months, actually about 4 1/2. He's in a highchair at our meals because it put him at eye-level with us, while freeing up everyone's hands to actually eat. (He was not happy in an infant seat because it was too low.) He plays with toys and a toddler spoon (short, fat handle, wide spoon part) during our meals and "talks" to us. He's definently a happy part of family meals without the food at this point.
