Last year, a trip to Cancun during spring break would mean nonstop partying for Nicole “Snooki” Polizzi – but times have changed.
“She’s having fun soaking up the sun with non-alcoholic drinks,” a source tells PEOPLE. “She’s not drinking alcohol; she’s getting a lot of rest.”
“She would never do anything to endanger this baby,” the source continues. “She takes it very seriously and is doing everything she needs to and more to have a healthy baby.”
The reality star also made time for some fun with dolphins, getting up close during an encounter on Isla Mujeres.
Adds the source: “Her next vacation will probably include her making sand castles on a beach with her baby and [fiancé] Jionni [Lavelle].”
