Advice on drinking gainer shake for beginner feedee

Hi,

Need some tips here. I'm a new feeder. Managed to encourage wife to gain weight. She's not that enthusiastic, but I guess she's ok with her husband's preference.

Only on second night of before-sleep gain shake drink. I had prepared about 800ml of 1000 kcal gain shake. My dear wife was complaining on the amount she had to drink. I was actually diluting the shake since she had complained on the thickness of the whip cream on the first night, but I guess the diluted 800ml shake may not be as easy as it seems to finish in one-go. Appreciate any recommendations,

Thank you.
