Everyone knows children outgrow their clothes and shoes quickly. Less discussed is how fast children can outgrow their beds. If your little one has outgrown his or her crib and is ready for a big-kid bed, keep reading. These are a few simple tips that will make it easier for your child to transition to a bigger bed without the hassle.

1. Prepare yourself.

Financially and time-wise, you'll need to prepare for this change. Budgeting for a new bed means saving for it. You can  snag a Sleepy's mattress for as low as $149, so you don't have to break the bank to get a new bed. Next, take your child shopping with you. Let him or her test out beds and roll around on the mattresses. You may be the one making the final decision, but allowing your kid to come shopping with you lets them be involved and introduces them to the idea of a new (and bigger) bed. And at Mattress Firm, your son or daughter will get a certificate certifying that they're now a big kid.

2. Think long-term.

When it comes to a new bed, it's important to consider the future. A twin bed may suit your child's needs right now, but you might have to buy another mattress sooner than you think. Choosing a queen mattress now will give you more of your money's worth later, and it'll be an investment that fits your child's body for years to come. You'll thank yourself later, trust us.

3. Essentials, essentials.

You'll probably need new sheets, new pillows and maybe even guardrails to wean your child out of the crib and onto the new bed. Rails ensure that you won't stay up all night worrying that your child could roll out of bed, and they are reminiscent of sleeping in a crib. This can make the transition easier for your little one. If the room doesn't already have a night light, you may want to add one at this point.

4. Refresh the room.

Once you've purchased a new mattress, you can rearrange your child's room. Make sure to leave a few key items in place—ones that your child will recognize. This will allow him or her to feel more comfortable approaching and sleeping in a new, larger bed. Old toys, blankets and other trinkets that your child is attached to will help them feel right at home. Make sure to schedule for ample time to get your child in bed, especially on the first night of sleeping on the new mattress.

Children grow quickly, and these changes can feel overwhelming both emotionally and financially. However, considering your future needs now and preparing and budgeting for the big (and little!) changes makes all the difference. With these tips and some planning, your child's transition from a crib to a big-kid bed will be smooth sailing. Or sleeping.
