Preschoolers like to ask questions—but if you're pregnant with a preschooler in tow, you might be surprised what your preschooler really wonders about.

Melissa Summers of Fontana, California, expected her preschool-aged son, Jake, to have a couple of questions when he accompanied her to a doctor's office visit before the birth of her youngest son, Brandon. Instead, young Jake listened to the baby's heartbeat and fidgeted in the chair. When he struck up a conversation with the doctor's aide about his soon-to-be younger brother, his concern was his mother's poor choice for names: the young Star Wars fan really wanted his new baby brother to be named Anakin Skywalker.

When it comes to preschoolers questions about pregnancy, you might be surprised at what they really care about—don't worry it's usually not where babies come from.

Knowing When to Tell

"There are two camps of thought when it comes to telling your child about your pregnancy," explains Dr. Susan E. Caudle, PhD, a clinical psychologist at Texas Children's Hospital. "The first camp is to wait until you start to show and the child asks questions." Moms-in-the know and doctors alike usually suggest waiting until at least the second trimester because most complications and miscarriages occur during these first few weeks.

The second camp, explains Dr. Caudle, is to tell your child early in the pregnancy, either because of your own excitement or because you are sick and want to explain to your child the reason.

Summers decided to tell her preschooler early in her pregnancy, at six weeks. "I wanted him to understand why Mommy wasn't feeling well."

Whether you decide to tell your preschooler early or later in your pregnancy, Dr. Caudle emphasizes that you give some explanation to your preschooler about why you are sick or fatigued. "Preschoolers tend to come up with their own reason for something if you don't clarify it, and their explanation tends to be far worse than what is really happening."
