Big sister was right there for Khloe when she was giving birth.

Kim Kardashian West is so pleased she got to “return the favour” of holding her sister Khloe Kardashian’s legs up while she delivered her daughter.

Kim was by her younger sibling’s side when she delivered her baby girl in the early hours of Thursday morning and couldn’t wait to gush about how “easy” she made it look.

Taking to her Twitter account on Friday, she said:

And to show her sister how proud she was of her, the 37-year-old beauty sent her a lavish baby bundle worth $8,000 so that she had something nice to come home to.

According to TMZ, Kim – who has four-year-old daughter North, two-year-old son Saint and two-month-daughter Chicago with her husband Kanye West – sent Khloe a Noitte Fatata custom bassinet from baby boutique Petit Treso worth $5,000, a range of organic bath products costing $1,000 and blankets worth $1,500.

Khloe, 33, was due to give birth to her baby girl at the end of the month, but she went into early labour due to the stress of her boyfriend Tristan Thompson’s alleged cheating.

Despite the drama, Khloe allowed NBA star Tristan – who also has 16-month-old son Prince Oliver from a previous relationship – into the delivery room.

A source said: “Khloe laboured yesterday at the hospital. Tristan was there for the birth. He has practice today, but will spend as much time at the hospital as possible.”
