Although it is tempting to neglect your baby, there are some potential negative consequences. If a bouncy seat looks convenient (such as the one below), don't be fooled. Even if it saves you having to hold your baby and play with him all the time for the short term (or maybe keeps him from getting stepped on while you run after his older brother), it will cost you a lot more work later. Trust me on this one.
Because the chair encourages the baby to stay in one position for a long time, if the baby starts favoring one side of his head, he could develop torticollus (tight neck muscles that keep the head turned in one direction) and plagiocephaly (a flat head). He might even have to wear one of these:
But even if he doesn't need the helmet, he will need to go through extensive physical therapy sessions, as well as rigorous exercise regimes three times a day. There might very well be six different stretches that force you to play with your baby, keep him happy, make him laugh, sing to him, and spend way more time with him than you normally would, all while stretching him. For the lazy parent, this might be quite frustrating. How can you Facebook and blog (or maybe even clean a dish or two) if you have to spend quality time with your kids? Life is tough.
Another potential drawback of said condition is that you should really avoid putting your baby on his back unless he is sleeping. This is inconvenient. Since tummy time gets old fast for your baby if he is left on the floor by himself, you will probably have to spend that tummy time playing with him and keeping him happy as well. You may even, as a result, be forced to bond with him and get to know him in ways you wouldn't have bothered with before.
And finally, you will need to fork out the cash to buy a Bumbo chair for whenever you really can get away with neglecting him (or maybe when you have to feed his older brother or finish the laundry. not that that would ever happen). Don't be fooled by the Bumbo, though. It strengthens his neck muscles, but you still have to keep an eye on your baby so that he doesn't fall out.
Moral of the story is:
Forget the bouncy chair. In the long run, it will cost you more time and money than it's worth. And it will force you to spend many wonderful hours getting to know your baby and falling more and more in love with his adorable smile.
