I feel that we can't expect too my h from mother in law because we are not their daughter, if they help it might seems like chore to them. Some more your mother in law from Malaysia she may feel even more reluctant?
I suggest train your husband to take care your baby. Start by while both of you at home your ask him do then you monitor. Slowly he will pick up n practice make perfect. My baby is 3 mths now and is my second child. My husband never know how to sponge baby. He never did that for my eldest son. During my maternity, I everyday busy like mad with my eldest son n baby during evening. There is once I ask him help to sponge baby, since then he always help me. He dont knownbut he learb.Finally I can more time to do my things like pump milk, have dinner, shower etc.
Try to learn to let go so that others can help to ease your burden.
