MIL thinks I’m being unreasonable!

OK, sure - I can see that now!

Sorry, OP - my post was really to the 'sun is fine' brigade. I do think if you are mindful of it though that is a good thing.

But I'm sorry if you feel very anxious with your LO, op. I hope you have people around you who are supporting you rather than just calling you 'silly'.

Maybe she's not an authority, but someone you're talking to and spending time with giving anecdotal evidence and an opinion based on experience of the thing you're worrying about is usually helpful and accepted.

And the baby belonging to OP doesn't necessarily make her judgement the right one either. Parents never automatically know best due to their status, especially so before they've learned much about being a parent.

We take advice from all sorts of people, sometimes experts and sometimes just one step removed.

Most replies here have agreed with MIL; OP seems overly anxious, MIL doesn't seem to have particularly interfered but shared a view and on balance this really something just to take on board.

i get it’s not the done thing out if you look at Ops posting history she is very anxious. And last weeks was worrying about a few minutes in the sun around the same time on a walk.

I suspect she is still worrying. About that ‘incident’

Not sure is an idea to start talking about getting skin cancer to someone who is clearly anxious, when there’s no evidence a few minutes in the late day sun will cause the baby to get skin cancer when they are grown up.

I think those saying sun is OK have not been diagnosed with a melanoma or basal cell carcinomas in their 40s or 50s - as a direct result of repeated sun exposure as a child.

Sure, a bit of sun is very pleasant, but if you want to err on the side of caution with a very LO, the OP's is not an unreasonable viewpoint. It is good to get into careful habits around sun exposure.

So MIL are not allowed an opinion ever?

Team MIL

It’s not that the guidelines aren’t roughly fair, it’s that it really really won’t hurt for baby to be exposed to daylight briefly at 5pm. I’ve just scrolled back through pictures of my 5 week old pfb on holiday in france, and while I was very very prb and carefully covered him up with a muslin carrying him in the midday July sun, by 6pm he got to peek out at the world around him and lie on a towel on the beach. Lovely memories!! He’s very fair skinned.

Is your baby a vampire OP? If not, I'm with your MiL

I think a hat. Light clothing and sunscreen would be ok. Obviously don't sit them
In direct sunlight but in the shade is fine.
Don't overthink it when mine were little and they never burnt

They shouldn't get vitamin d from sunlight, nobody should be relying on that
Most people are deficient and you should take vitamin d. I got sun, my friend works outdoors, both of us deficient
It's taken 4000IU daily to get my level from 9 to 66 and that's with 3 years of supplementing!

One of the strangest things I found when I moved to the UK was how it gets hotter later in the day. I walked home from work at 5pm last and the sunlight was glaring and I definitely could have burned. I don't know if that's just southern England thing but I put sunblock on halfway through my walk. So I don't think the time of day really makes a difference

Your mother-in-law needs to keep her mouth shut, but the hysteria over any kind of sun exposure, for anyone, is absolutely mental.

It's better to be over cautious about very young babies and the sun. Their skin is incredibly delicate, not at all like an adult's. I'd carry on as you are, OP!

This! Posters saying baby won't get enough vitamin D - it isn't advised that very young babies get their vitamin D from sunlight

5pm can be quite hot still. I put ours in just a vest, in the pram with a parasol clipped on. If we were standing around/ sitting in a cafe etc I'd always make sure they were in the shade but just walking around I wouldn't worry

It’s been reaching peak temps at about 4pm in London over the past week, high 20s. I’ve been keeping my baby out of the sun at 5pm too as it still feels pretty strong to me. Guess it depends where in the country you are and what the weather’s been like.

At 10 weeks you're right that a baby should not be in direct sunlight. I'd have skin covered with light fabrics and a shaded stroller/umbrella of some sort.

I'm with your MIL. Your baby is going to end up with vitamin D deficiency

I've always covered under 6 months olds in direct sunlight. Didn't stop us going out but skin covered. Either covered by clothes or with an umbrella as a parasol. Always placed in the shade not direct sunlight if on a blanket on the floor etc.
Most people I know have dine the same.
Older the 6 months ok but with suncream and period in the shade.

I agree with MIL, 5pm sun in the UK is fine and assuming you're not just leaving the baby to bake directly for hours I can't see a problem.
I don't think I ever read the NHS guidelines, even if I had they are mostly just that - guidelines, not rules!
I think you need to relax a bit.

Im with your MIL but it’s your baby.

Just because she's done it before doesn't mean she did it well or makes her the authority, it's not her baby, assuming op didn't ask for her opinion either and it's none of her business.

Doesn't matter really, baby is yours and she doesn't have any rights to make choices like this.
Baby should be getting enough vitamin D from your breastmilk if you're taking a supplement or formula.

Tell her to butt out, none of her business.

Babies until 3 months old do not have sufficient skin barrier that adults do - so avoid adult soaps and shampoos, avoid washing with anything but your own hand (sponges are a no no) and sun exposure should be avoided at all times. As for Vitamin D it is passed via breastmilk or mixed in oil form into bottle feeding.

I'm with MIL too. Obviously some sense is needed but 5pm in UK is fine.

I was advised to put my jaundiced newborn in the sun, do they not do that anymore?
