Poor Pie is having a reaction to mozzie bites.

To begin with they were just larger than normal.
Then she had a couple which apart from being very swollen & lumpy (maybe 1cm across) looked almost blistery, and as they faded they became mottled & looked almost bruised.
I asked the Gp (not our regular Dr) when we were there for something else & he said it's normal & she will grow out of it.
But it has gotten worse each time she's been bitten.

Yesterday she got bitten twice (no idea where or when, I only noticed it this morning) one on the back of her hand, and her entire hand is puffed up, as well as one on her arm and it is swollen in an area of about 6 - 7 cm and red & hot to touch.

Is this really normal?
I am thinking about taking her back to (our usual) Gp.

Also if anyone has a really good effective repellant they can recommend I would love to hear of it.. has to be safe for a 14mth old, and preferable something natural, not too many nasties.

TIA.
