Children love to go to on trips to the playground, once your little one can sit upright you can put them in one of the swings and push them gently to and fro.
Playgrounds usually have special areas for babies and toddlers. Keep to them, as older children as we all know play more boisterously. Watch out for children running behind the swings, we have all seen what can happen when a running child makes contact with a moving swing.
If there is a baby slide, your child will enjoy going down on it, with you holding them firmly at all times. Check to see that the slide is made in one continuous piece with no jointed panels and that the surface beneath is designed to cushion any falls.
