Sure, her children aren't babies anymore, but that doesn't mean Britney Spears and Kevin Federline aren't still co-parenting. It's been a rough road both in terms of their relationship (especially with their reality TV show and all that chaosand in terms of Britney's career and personal path.

But now that the Federline boys are older -- and speaking out on social media about their mom's legal and other troubles -- what does Britney think of how her ex raised them?

How Did Kevin Federline End Up With His And Britney's Sons?

It's been a while since Britney Spears has really spoken up about Kevin Federline. At first, after their split, she was busy dealing with her personal demons. So while she was still involved with caring for their little boys, she had less time to spend with them than most moms would like (and less than what Britney has said she wanted, too).

But amid all the drama, and Britney losing custody of the boys after specific events unfolded, Kevin had to take over much of the childrearing responsibility. He wasn't a new dad at the time, either; K-Fed already had two children with his ex.

Fans seem to think Kevin Federline has a great relationship with his kids -- and not just the ones he had with Britney. After all, he has a total of six children now; two with ex Shar Jackson, then two with Britney, and his most recent two with his wife Victoria Prince.

So Kevin was able to have his four kids grow up together, without a lot of interference from Britney. While Britney's father definitely got involved -- and apparently handled the child support payments that resulted from Kevin gaining custody -- the actual parenting fell to Federline.

What Has Britney Said About Kevin's Parenting Skills?

These days, Britney doesn't say much about Kevin's parenting. In fact, she seems to think pretty highly of him. And she's always gushing about her boys, even if they do find her 'embarrassing' these days.

But back in a long-ago interview, when the boys were still toddlers, Britney seemed to have concerns about how Kevin was raising their sons. In a 2008 interview, Spears admitted that the kids -- who were 2 and 3 at the time -- were "starting to learn words like 'stupid'."

In Spears' defense, she elaborated, the boys didn't "get it from us" (it's unclear who "us" meant in that context). Rather, Preston saying "the f-word now sometimes" seemed to have come from K-Fed.

Britney, in fact, explicitly stated, "He must get it from his daddy. I say it, but not around my kids." Still, even then, Britney called her boys "special people" -- mentioning that she enjoyed "every time they come to visit me."

The publication even noted at the time that Britney didn't discuss the rumored conservatorship, but she did say, "I didn’t think my husband was gonna leave me... Otherwise I’d be with my babies 24/7."
