Police are investigating the death of a 6-month-old boy at a San Antonio daycare.

CNN spoke with the parents of that little boy who say this could have been avoided.

“We were about to do some nice happy things, and now, we have to bury our little boy,” father Richard Donnell said. “It’s just tough.”

Donnell’s nightmare started Tuesday afternoon when his 6-month-old son’s daycare called him.

“Got a phone call around 1 saying that our son was unresponsive,” Donnell said.

The big, green-eyed Michael Carter Donnell died before his parents could get to him.

“It looks like he just choked on all his vomit, and it just looks like nobody was watching him at the time he was suffering.”

Young Michael Carter had just learned how to roll over and his parents say they warned staff at Our Little Hopes and Dreams that he often throws up while doing it.

“He just started rolling over and every time he’s on his stomach, he throws up a little bit,” Donnell said. “We let them know that. Don’t let him be on his stomach, and that’s exactly what happened.” 

According to police, daycare staff did perform CPR and other life-saving efforts, but the baby’s family says it was too late.

He was taken to a local hospital where the 6-month-old was pronounced dead.

“Something wasn’t done right. We want answers,” Donnell said. “You know, we send our child to be taken care of and looked after, not the opposite “

A director at the daycare was reached by phone but declined an interview.

She tells CNN the entire staff is in shock over this loss, and they are still trying to figure out what happened as well.

“I wouldn’t recommend nobody sending their child there anymore,” Donnell said. “You know, this shouldn’t happen to nobody.”

Police say the case is still active and ongoing.

They are waiting on autopsy results which will help determine how to proceed.
