One of the most nerve-wracking things parents have to worry about is how their kids will adapt to having a new brother or sister. It's a big change, and some kids aren't very welcoming to their new siblings.
New mom Alexa Crahan was so worried about this, she found herself crying before her son Logan was introduced to his new brother Liam.
It turned out she had nothing to worry about, as this adorable video of their first meeting shows.
What a welcome! Logan was even wearing a shirt that said "big bro."
As you can imagine, Logan has proved to be a great big brother. His dad Alex says that he's been hugging and offering to help care for Liam since the moment they met.
