I just had a child on July 2019 and would like to know if I should claim 7 allowances on my w4 form? I used the worksheet provided in the w4 to determine the number.

1 for "myself"
> 1 for "head of household"
> 1 for "single and with only one job"
> 4 for "child tax credit with under $71,000 in income" (says to put 4 for each child.
