Will new baby develop allergies like sibling?

[Fontainebleau007]

Hi all just wondered if any of you have an insight with this.
DS1 no allergies
DS2 anaphylactic to pistachios

I'm pregnant again and wondering if the new baby will be more likely to develop an allergy like DS2?
I'm so nervous, any info will be helpful x

Allergies are often hereditary, so there's a high chance yes.

Are you under midwife or consultant care? My DS has allergies and I was under consultant care during my second pregnancy, I asked for a referral for an allergy panel for DD when she was born and we got a referral to immunology for when she was 3/4 months old.

There was a very interesting article on BBC news about this recently, not the genetic link, minimising the risk of allergies in high risk children. here

Thank you I've only just found out I'm pregnant but will definitely mention it when I get my appointment x

That's interesting thank you x

First child, anaphylactic to dairy/sesame/coconut

Second child, no allergies so far touch wood

There is some interesting emerging research that suggests some protective factors for children prone to allergies are breastfeeding and probiotics for baby and yourself during pregnancy. Some factors likely to influence negatively are antibiotic use for yourself during pregnancy or at birth or for baby during first year. I can’t link research right now as on bedtime but will do later

That's great thank you so much x

I’ve actually been seeing privately the doctor who led the research in the article.

DS1 had really bad allergic reactions when I was weaning him so I was worried about DS2. I got a skin prick test done on him before we started weaning and then on the advice of the doctor in that article, I give him allergens every week to avoid him developing an allergy later on as he is at higher risk because of his brother.

@MistyHedgehog that's interesting thanks I did just read something about giving allergens when weaning x

suggests the use of probiotics for baby from birth, Colief multibiotic drops arw good and have the specific strain which may prevent allergies. You should also take throughout pregnancy, BioGaia are good for you.

Thank you!! X

Interesting reads there thanks. Really appreciate it 😊

No problem, I know how scary it is having a child with allergies and you will do anything to try and mitigate the risk for your other children. It’s all pretty new research but I’ve done it anyway and maybe that’s contributed to him being allergy free so far who knows 😂 good luck with it and congratulations on your pregnancy x

That's brilliant! It really is scary so will definitely do anything to try and reduce the risk! Thank you so much ☺️ xx

I have friends with multiple anaphylaxis children and friends with one and the others have no allergies.

My daughter has multiple delayed allergies and it did make us question whether to go for a second. We decided to go for it when we felt emotionally read to go through the allergy process again. Our second could be the same as our first but because of our first we are not the same and I think we would cope and manage the whole process better. Her allergies were evident from birth bit weren't diagnosed until 17 weeks.

I have a histamine intolerance and have had non-immune anaphylaxis due to eating high histamine foods so there's clearly something in the genes

Hi all just thought I’d come back and update this thread. Unfortunately I had a MC at 6 weeks. Thanks all for you experiences it will definitely be worth keeping in mind if we decide to try again x
