In one sentence, describe what the following article is about: Babies younger than a month old should be kept at home until they’re ready to be exposed to the sun and terrain of a hike. The jolting of the carrier during a hike can injure a newborn because they are unable to hold their head up without assistance. If you’re a mother, you might also want to wait about a month after giving birth to get back on the trail. Check with your doctor to see when it’s safe for you to resume physical activity like hiking. Depending on the length of your hike, you might need a few different snacks for yourself, like granola, fruit, or protein bars. Be sure to include ample water for yourself and the baby, and pack small snacks and a few jars of food for the baby as well.  This is especially important if you’re breastfeeding, which uses a lot of your body’s energy for producing milk. Be sure to bring enough food to keep your energy up, and pack an extra empty bottle just for water for the baby. If you aren’t breastfeeding, try to pack powdered formula, which tends to be lighter and easier to pack. Even if it’s warm outside, dress your baby in a long-sleeve shirt, long cotton pants, and a wide-brimmed hat to protect them from the sun. Dress in your normal hiking clothes, and be sure to prepare for the weather by taking a jacket or spare t-shirt just in case. Wear sturdy hiking shoes or sneakers.  Don’t forget to bring extra diapers for the baby! Chances are, you’ll have to change them on the hike if your trip is longer than an hour or so. At the very least, you may need to change them before and after the hike. Try to avoid putting sunblock or bug repellent on babies that are younger than 6 months. It’s best to rely on clothing for protection from the elements. The great outdoors can be very unpredictable, and even a minor change in temperature or a random rainstorm can make your hike a lot more difficult. Keep a close eye on the weather in the hours leading up to the hike, and plan accordingly. If the weather is supposed to be bad, don’t take your baby on the hike. If the weather begins to change during your hike, it’s best to turn around and make your way back to a safe spot as soon as possible. Even if it’s a false alarm, it’s better to be safe than get caught in a dangerous storm.
Summary: Avoid taking your baby hiking if they’re less than 1 month old. Make sure the everyone on the hike has enough food and water. Dress yourself and the baby in clothes that are appropriate for the weather. Monitor the weather closely using a weather app.

Problem: Article: Making a sound on a trumpet requires more than just blowing air into it. Use the proper lip technique for the best tone. Start by saying the letter M, and holding your lips together right when they touch each other. Then tighten the corners of your mouth. This is the starting mouth position for trumpet playing.  Don’t pucker your lips. Keep your mouth straight across. Keep your jaw loose and don’t clench your teeth. This buzzing produces the trumpet sound. Use your diaphragm and push air through your lips while keeping them clenched. Produce a buzzing sound as your lips vibrate.  Imagine the noise you’d make if you were imitating a mosquito buzzing. This is the sound you want. Don’t change your lip position like you would when you blow air out. Keep your lips together so they vibrate and buzz. Avoid puffing out your cheeks. Lick your lips first if you’re having trouble getting this sound. It won’t work as well with dry lips. When you’ve gotten comfortable buzzing your lips, get a feel for blowing into the trumpet mouthpiece. Take the mouthpiece and press it against your lips gently. Maintain the same mouth position as before. Then buzz your lips into the mouthpiece.  The mouthpiece won't produce much sound by itself, so don't worry if notes don't sound good yet. The mouthpiece detaches easily. Just twist it loose a bit while pulling gently and it will come right out. Do the same to put it back in. Don't hit it in or it may get stuck.
Summary:
Press your lips together and keep the corners of your mouth tight. Push air through your lips to make a buzzing sound. Blow into the mouthpiece when it’s not in the trumpet.
