If it's family planning you're qorried about, I believe the right person to talk to would be your partner himself. In my opinion, RM10k for the both of you and a child is acceptable unless you are asking for a lavish lifestyle. At the end, what is your priority? RM10k can afford the both of you a low range family car for each of you, or a more comfortable+safer+bigger car for just the both of you. It can pay the installment of a outskirt double storey house. And there will be enough to look after the family. Afterall, if he has the ambition, he won't be earning RM10k for the rest of his life right?

Your role as a mother after pregnancy also involves mental support for him. Don't pressure him for so much unnecessary household expenses etc. If he is responsible, he will save some for a rainy day and for when the child grows up. Of course, that doesnt mean he forgets all the romance ie. buying the occassional flowers, nice dinner, holidays. Just don't do it lavishly or overspend.

Btw, if you say with RM10k, he barely has savings, something is wrong with his spending. Gambling? Heavy spender? It's impossible not to save unless he spends it all on unnecessary luxuries. Remember, it's how he spends it that's important now, not how much he earns. Someone can earn RM2-3k for month and still save RM500-RM1,000. It really depends on the person.
