Arguing with sister in law over DS age

[Janedoe95]

Please do correct me if I’m wrong -

my DS is 6 months born on the 10th

I work out his age by weeks at the moment so 24 weeks = 6 months

but she says he’s not 6 months as it’s not the 10th yet?

am I the only one who calculates age like this? It aligns with his vaccinations and nurses haven’t said I’m wrong.

obviously I understand when he’s older every year on the 10th will be his birthday but from what I understand it’s calculated weekly as babies can change so much and grow so fast

I'd probably agree with your SIL, he'll be 6 months on the 10th

I agree with everyone else - he'll be six months old on the 10th.

Good point

• Not all months are the same length.

• 4 weeks does not equal one month.

• 6 months is half a year if you really want to do that in weeks then it's 26 weeks.

You child is not 6 months until the 10th.

You are incorrect.

I also agree with everyone else - he will be 6 months on the 10th

Your SIL is correct, but I can't imagine a situation where this matters or anyone cares. Medical staff will have his date of birth, let them worry about the age calculation if they really have to.

A month is not 4 weeks. His weeks and months won't really line up. Use whole months from 6 months

You're wrong, she's right. Like others have said 26 weeks is 6 months not 24 weeks. Surely nobody counts 4 weeks as a month?!

Um.. why does it matter? Is she worried you're you going to start weaning 3 days early?

This

What everyone else said about the 10th being when he is 6 months but it doesn't really matter being that precise for anything.

I only counted in weeks till about 3 months.

Hours till 1 day
Days till 2 weeks
Weeks till 3 months
Months till 18 months
That's what I roughly used!

its 6 calendar months from 1st January to 30th June which is
31 + 28 + 31 + 30 + 31 + 30 = 181 days = 25 weeks 6 days

it is also 6 calendar months from 1st March to 31st August which is
31 + 30 + 31 + 30 + 31 + 31 = 184 days = 26 weeks 2 days

Half a year is also 6 months which is 365 / 2 = 182.5 days = 26 weeks + 1/2 a day

So there are several different ways of calculating 6 months!

Not every month has 4 weeks in.

I agree with your SIL.

A month can be 4 weeks or alternatively a calendar month like January/ February. She's a bit unreasonable to be so pedantic about a few days though and sounds like hard work!!

I would say if he was born on the 10th then the amount of months he is changes on the 10th. That's how you would get to his first birthday which is the day he turns 12 months.

26 weeks is also 6 months not 24. I'm afraid I'm with you SIL on this one.

It really isn't worth an argument.

A lunar month is 28 days. There are 13 of them in a year. Gonna get awful confusing when he is 13 months old on his first birthday!

Its certainly not worth forty posts all saying the same thing.

Why does it matter ?

I cannot stand the counting in weeks business after about 6 weeks. It just sounds odd imo.

Also people who say 'DC is 23 months'. Just say nearly 2 🤦🏻‍♀️

You and sil need to find something else to discuss? Music? Sport? Films?

To add - a child born on 10th March will be
21 + 30 + 31 + 30 + 31 + 31 + 7 days old today ie 181 days = 25 weeks and 6 days. They will be half a year old tomorrow in terms of number of days ‘ complete weeks, but in monthly terms he won’t be a full 6 months until the 10th.

It’s totally irrelevant how much baby changes or grows. Baby will be 6 months on the 10th. You are wrong.

6months on the 10th. Hard to believe this is actually a question

He's almost 6 months 🤷‍♀️

6 months on 10th
