"Jessica loves this baby with all her heart and is determined to be the greatest mum ever," a source told OK! magazine. "She wants to go [to church] every Sunday so the baby has a strong spiritual foundation."

Jessica is also interested in fostering her tyke's intellectual ability.

The proud parents are preparing their baby for great expression and achievement.

"She and Eric are already picturing mother-daughter duets for Grandma and Grandpa," the source shared. "[Jessica] knows classical music boosts the baby's IQ, so she was singing and putting headphones on her tummy and playing Mozart so the baby could hear."

According to In Touch she is splashing out $500,000 on a birthing suite, $100,000 on food and room service, $14,500 on a crib and nearly $70,000 on a private jet for a possible trip back home to Texas.
