we had chippy tea tonight and dd (3) was the last to finsih so i left her at the table finishing off whilst i washed the plates, i heard her having a major coughing fit so i came in and she was ok, thought she might of had an issue with a chip anyway was just putting her to bed and when iw as reading to her i realised she smelt of vinegar, have put 2 and 2 together and realsied she has had a swig of the vinegar so what i want to know is, is this ok? dh doesnt seem concerned...
