Bags under DD's eyes - but not tired

[HollyFP]

DD is almost 6 months. This morning I noticed she has puffy eyes/bags. :( She has regular daytime naps, and sleeps fairly well at night, from about 8.30pm-8am with a bf around 4am.

I've just started BLW very gradually, so she's has bananas, avocado, cucumber, courgette and toast.

Could it be a reaction to the toast? There are no allergies in me or DH or in our immediate family. How do I check if it is an allergy reaction?

Would it help if I tried to get her to sleep more, or is this nothing to do with it?

TIA

Or could it be teething perhaps?

Bump

it does sound allergic to me, especially related to starting weaning, I'd maybe remove the foods one at a time and see which helps!

She hasn't reacted to anything at all in her life so far, has never been ill or shown any allergy symptoms. I gave the toast on Saturday lunchtime...would that fit in the timescale for an allergic reaction?

I can't think of anything different over the weekend...the puffiness has gone down since I first posted. Maybe sign of a cold or something?

Now she's had a bit of diahhreoa, not sure if it's related...
