For Dr. Marcie, you can't start practicing too early. While your baby's in the womb, you can begin building habits that will work not only when things are fine and lovely, but also when you're facing an epic potty-training crisis. Building a solid foundation for interacting with your kids can make life a lot more fun, because you know what to expect — and so do they.
If a quick DIY play yard better suits your requirement then make one at home with an inflatable plastic kiddy pool. In case you have a kid’s plastic pool lying around in your house, then you can inflate it and convert into a play yard. Simply inflate the plastic frame, place a soft blanket or mattress inside it, and you just made a safe and comfortable place for your baby to play. Just make sure the walls of the pool are high enough to prevent your baby from crawling out. Also keep all sharp and pointy things away from the pool.
Do not use the play yard once your baby has outgrown it: Stop using the play yard right from the day your baby outgrows the recommended age. You may be tempted to use it for some more days or weeks but this can be very dangerous since play yards are designed to meet the specific height and weight requirements of babies of certain age. The build materials may not be able to sustain the increased weight of a baby who has outgrown the recommended age of the playard thus posing a risk of injury.
