Kelsey Grammer is struggling as a new dad after injuring his foot playing tennis.

The former Frasier star, who became a father for the sixth time last week (ends25Jul14), admits he's finding parenthood to be a real pain this time around as he has to spend much of his time in a wheelchair.

He says, "I'm in a lot of pain but I'm Ok... I've ordered a wheelchair so I have to push the baby around... I also have a two-year-old daughter and she's a little more challenging right now, physically, because this thing really hurts. I'll have to put her on my lap as we fly through the house."

And his situation hasn't been helped by his wife Kayte's insistence they don't need a nanny.

Grammer is in so much pain, he has called in a registered nurse to help him get around.

Hobbling on to comedienne Chelsea Handler's late night show on Wednesday (30Jul14), he added, "I cannot be this way."
