"Ventured into the office for a few hours today, but raced home to see Arabella this evening," she tweeted Monday. "I'm already experiencing separation anxiety!"
The 29-year-old jewelry designer, who married New York Observer owner Jared Kushner in 2009, seems to be adjusting to motherhood quite well. "Enjoying a mellow night at home with my husband and baby," she tweeted Saturday.
Trump and Kushner, 30, are determined to make sure their daughter is raised with a good set of values. In the June issue of Harper's Bazaar, Trump acknowledged that as first-time parents, "we have our work cut out for us to ensure that our daughter is grounded and not spoiled."
