After attending Robin Thicke’s wedding over the weekend, Kelly Stafford returned home feeling completely drained.

Kelly, 36, and her husband, Los Angeles Rams quarterback Matthew Stafford, were among the guests at Thicke’s marriage to April Love Geary in Cabo San Lucas, Mexico, on Friday, May 30.

“I need breaks from my kids just like anyone else,” Kelly admitted on the June 5 episode of her podcast, “The Morning After,” while reflecting on the couple’s three-day escape.

Back in Los Angeles, Kelly had to face an ongoing challenge with her 4-year-old daughter, Tyler, something that she said has been “weighing on me for six months.”

The issue centers around Tyler’s nightly insistence that her mom sing “Twinkle Twinkle Little Star” before bed.

“I keep telling myself, this won’t last forever,” Kelly said. “But I’m just so exhausted. It hurts to say, but even a few extra seconds with her at night feels like too much. That’s such a terrible thing to admit.”

She continued, “I feel like an awful mom because she’s just asking for one simple song before bed. These days, I probably do it once every four times she asks.”

Married in April 2015, Kelly and Matthew, 36,are also parents to 8-year-old twins Sawyer and Chandler, as well as 6-year-old Hunter.

“I want to do better,” Kelly said. “I’d only been back three days, and she asked me to sing. I did it, but I wasn’t excited about it. Isn’t that awful?”

She went on, “I need to remind myself she’s still a little girl—just 4 years old. I have to try harder with her and show more patience. Because both Matthew and I are feeling drained by her constant chatter.”

Kelly explained that Tyler wasted no time showing off her endless talking once the couple returned from their trip.

“As soon as we walked in, Tyler—bless her—kept repeating, ‘Can I tell you something? Mommy, can I tell you something? Guess what, can I tell you something?’” Kelly said. “Five minutes in, I told her, ‘Tyler, I need quiet. Just five minutes.’”

Things have gotten so overwhelming at home that Kelly and Matthew had to create some new boundaries for their daughter.

“We made a rule that she can’t talk until after she finishes her meal,” Kelly said. “Otherwise, she’d talk through dinner and barely eat a bite.”

She added, “Forty-five minutes later, she’d still be sitting there, finishing dinner alone because everyone else had left.”
