The couple welcomed Kabir in March, and it's his first Christmas.
"Amrapali and Kabir have made my life special by entering to my world. I always want to bring love and blessings for them in every possible way I could. This is the first Christmas for my son, so I am trying to make it special for him. We have already started celebrating the festival and will continue till the year end," Yash said in a statement.
Amrapali, best known for her roles in shows like "Khushiyan", "Teen Bahuraaniyaan" and "Qubool Hai", said: "Yash surprised us by decorating the house with Christmas stationery. He also made the Christmas cake himself.
"He did all this when I went to visit my friend's house with Kabir and when we returned we were really surprised. I am really one of the luckiest wife to have Yash as my husband."
Yash and Amrapali, who got married in 2012, were seen together in "Nach Baliye 6".
