Hmmm. This is a good question. I've been thinking about it too, just because I'd like to make sure she's not allergic soon, since you'd be surprised what shellfish and fish show up in! I did try to feed my daughter tuna fish once and it was a no-go. Maybe try fish/shellfish in a really yummy way -- like fish sticks dipped in ketchup, or fried clam strips with tartar sauce... and definitely do it somewhere where you are close to the doctor/ER just in case!

I've given my 15 month old daughter most of the high allergy stuff. I can't think of anything I haven't given her!
My husband and I have no food allergies, so I was not as concerned as I would have been if we had a few of them.
I don't think tuna and other fish have the same affect as shrimp, crawfish or lobster. I hear much more about allergies to shrimp than tuna or tilapia for instance. I would recommend starting with a mild fish and even try a bit of shrimp to see if she's allergic. Separately though. If you do find an allergy to shellfish, she may still be fine with other fish. http://foodallergies.about.com/od/seafoodallergies/p/shellfish.htm

As for your MIL and the peanut butter, she's lucky your daughter wasn't allergic! I've been giving mine PB for several months, she loves it. My doc told me at her 1 yr appt to avoid it and I said "oh, well she's already had it a lot". He looked surprised and said to just limit it. I am thinking it's because it can be a choking hazard because she's obviously not allergic.

As long as you only introduce one possible allergenic product at a time, you should be fine. If you're allergic to a lot of things, be more careful!

My daughter has had almost everything I think...I like chinese so she's had shrimp lo mein and fried rice...and crab rangoon...all sorts of shell fish and only fish sticks because we don't eat fish..she doesn't love it but she didn't have a reaction either

I made a crab dip for a party that has cream cheese, sour cream, ranch dressing, worcestershire sauce, mustard, and a few drops of lime and lemon. I shredded the crab into it and gave DD a small portion on a cracker. She gobbled it up like you wouldn't believe. After you bake it all in the oven, it gets all gooey and yummy. If your child doesn't like mustard or the sourness of lime/lemon, replace them with chopped up roasted red bell peppers. It will also mask the smell of seafood.

You have to be careful with seafood, as too much will cause mercury poisoning. From what I remember- the smaller the fish, the less amount of mercury content there will be. Normally the safer kinds of seafood are the ones that kids won't eat- lol.

DD has bad hayfever and pollen allergies and our doctor actually suggested that we offer her (at 24 months) regional honey and fruit before the season starts. Small doses of it should lead up to a gradual immunity. Only time will tell, though if it actually works. It has been working a little bit for the hubby, who has the same allergies.

Here's a link to mercury levels in fish and shellfish.

Also, Jolene, honey isn't high allergy, you aren't' supposed to give it under 1 year due to the potential for botulism spores. After 1 year the body has the ability to fight it, but not before. So there is no reason to believe it could cause allergy in your daughter. Give her some honey! ;)

I found a site with the high allergy vs low allergy foods on it if you are interested. http://www.wholesomebabyfood.com/allergy.htm

If you don't normally eat it, than I don't see the reason for giving it to her, especially if it makes you nervous. She can try it when she's older.

We don't eat any fish really. I have gone out of my way to buy fish for her but she deosn't much care for it.

I want to give her honey, but it's crazy expensive and we are crazy broke. Lol. The doc told me no honey because some natural bacteria's can cause an averse reaction, I just took that as allergy, oops. But I do want to feed her honey.

I just don't get why shellfish freaks me out when peanut butter(didn't at the thought, but did when she was given it so young), eggs, soy and dairy haven't even fazed me!

I can't say that I blame you on the shellfish! I was nervous the first time I gave it to my daughter! I've given her several types of crab, shrimp and crawfish, but I don't give her very much. She loves it!

The fish I've given her most is tilapia, it's a good beginner because it's very mild tasting. Tuna is easier because you can get it in a can, but it has a stronger flavor. I think she may have had a few others at a restaurant , if I order something I let her try it. She tried some bluefish I got when we were at the beach, but it wasn't her favorite.
Fish sticks dont' really taste like fish, but are an easy way to introduce it too! There are lots of options!

Honey is very expensive! I was going to get some from the store today and it was $6 for this tiny little bear! wow!
Dont' stress too much about it. It is good to make sure she's not allergic, just so you know if you need to let others know to avoid it or not. You don't need to make a regular of it, unless of course you find that it's your DD's most favorite thing ever :) Mine was stealing my crab dip earlier today! lol
