If/when your kid gets sick (like with a cold/cough), there's very little that you can do. Most common medicines aren't approved for kids under 2. Consider buying a decent humidifier which can at least help keep their mucus more liquidity and help their breathing at night.

Every kid has different challenges that will really push to your limit at some point. Some kids have difficulty sleeping, some have difficulty eating, some have speech delays, some have gross motor delays, etc. You don't always know what your kid's particular difficulties will be but just keep working at it and do your best.

Start reading and singing to your kid as soon as their born. It's a great bonding activity and it's great for their brain/language development. You don't need a ton of books, you don't need to know a ton of kids songs, just do whatever you can.

Check out your local library (if there is one). There's usually lots of programming for young kids. They don't just have books, but sometimes also toys and other activities that you can check out. It's also a good place to meet and socialize with other parents.
