Close friend's first birthday celebration gift money

At my first baby's first birthday celebration, I only invited family and relatives, kept it simple at a restaurant, and didn't inform friends or receive anything.

Today, my close friend is having a first birthday party in two weeks.

Since I am pregnant with my second child and my body is heavy, and since our house is far away, I don't have to come.

I heard they sent the invitation because they thought it would be polite to inform you.

My friend's house is 1 hour and 30 minutes away from our house, and the same amount of time is needed to get to the first birthday party venue.ㅜㅜ

In two weeks, it will be the 33rd week, with a routine prenatal checkup in the morning and my mother-in-law's 60th birthday celebration in the evening, so we plan to have a meal.

It's a tight situation to coordinate the schedule for now.

Should I postpone my hospital visit in this case?

How much should I give as a congratulatory gift if I can't attend?

It's a night full of 고민~~~!
