sat or set


He sat at 3 month


He set at 3 mont

See example:

He sat at 5 month, started to crawl at 6 month, was able to stand up at 10 month and started to walk at 12 month.

I believe you are asking about the difference between "sit" and "set":


"sit" refers to the activity of sitting, as in he sits in that chair every day; he sat in that chair yesterday; he has sat in that chair every day this week


"set" refers to putting something else somewhere, as in he sets his book on the table every day; he set his book on the table yesterday; he has set his book there every day this week


So in your sentence, "He sat at three months" is correct.

'Months' should be plural, and the 'Oxford comma' is preferred for the last item in a series. In the US, we usually use 'sat up' in this context, but it may be different in other places.


He sat up at 5 months, started to crawl at 6 months, was able to stand up at 10 months, and started to walk at 12 months.

Lewis, I agree with your advice on this question except for one tidbit. When discussing a baby's development, there is a decided difference between "sat up" and "sat." If I say that the baby is able to sit up, that implies that he can move himself from a horizontal position to a sitting position. If I say simply that he sat, that means that when I place the baby in a sitting position, he is able to hold himself there unsupported.
