RED PACKET

I am not closed to my in-laws. I am a divorcee almost 2 years. Ex-Husb no where to be found. My child is not closed to my In-law side. If my in-law invite me for CNY, i will consider to go. But if they dont invite me; do i still to attend such thing? If we are invited, may i know how much red packet $$ do you give your In-Law?? Do you just give to one person or both?? Need some clarifications as i dont usually give, only my ex husband give when i was with him, for me i love baking; so i bring lots of goodies and oranges.
