Freelance work can be very part-time to more than full-time employment, but there are no benefits, retirement or insurance. Staff positions are rare these days. Even the most successful illustrator can find that their current style is suddenly unemployable. Many illustrators work full or part-time in another field to have a reliable income and insurance benefits.
Diversity is the key to surviving as an illustrator, so keep your options open to all possibilities. You may need to market yourself under different "pen" names and websites to keep your illustration identities separate. If you are interested in working in the field of children's illustration you will have a better chance of getting published if you can both write and illustrate at a professional level.
Don't forget to develop your own personal work - you will find inspiration there that will spill over into your paid work and you may find that your personal work is marketable, too. Explore new media, materials and ideas on your own to keep the joy in creativity.
While traditional drawing and painting skills never go out of style, it is wise of you to keep abreast of new technologies and trends. Re-inventing your style and techniques over time will keep your work lively and vibrant. Be true to your inner vision while adapting to the ever changing entertainment and publishing.
