Make sure you choose a faucet that is compatible with your bathroom sink. First, consider whether the faucet will be mounted on the sink, on the counter or on the wall. For sink-mounted faucets, count the number of holes in the deck of the sink (none, one or three) to determine which type of faucet will fit your sink.irst, consider whether the faucet will be mounted on the sink, on the counter or on the wall.

For an adult or an adolescent, carefully insert the tip 7.5 cm to 10 cm (3 to 4 inches); for a child, 5 cm to 7.5 cm (2 to 3 inches); and for an infant, 2.5 cm to 3.75 cm (1 to 1.5 inches). Inserting the tube too far into the rectum can cause perforation.
1 A similar technique can be used with a small syringe, pressing very slowly on the plunger as the infant sucks or licks.(V.w5)  A small syringe (1ml) with a fine blunt-ended catheter tip attached, cut down to about 0.5cm long can be used.
