"只能有一个人在家照顾孩子了,我们不想这样" hopefully both you and your spouse can find a job right after landing.
"让一方的父母也过去帮助照顾一下孩子呢" apply visitor visa for your parent(s), however if the reason is "照顾一下孩子", they won't get visa for sure.
If both you and your spouse have jobs, and parents can't come, then send kid to full time day care about 800 dollar per month, or hire a nanny to look after.
