你应该很忙，同一时间，在工作和照顾孩子。Is this grammatically correct?And how can I turn this into a qustion?

I am trying to understand how to use a verb + 到。e.g.看到了，吃到了。when is this different to 看了，吃了。？

Can I have some examples of how to use 做? I understand using in the context of as one word ( a verb). But want to know how to use in a sentence.
