DD (3 wo last Thursday) was a chilled baby with good weight gain who fed and slept well, had normal nappies, went down no problems and had a little wind but nothing major.
Following a loving lecture from my mother last week regarding calcium I considerably increased my dairy intake from last Friday (hadn't been having any milk or cheese and very limited yogurt for the first 3 week of her life as craving carbs and meat
).
Since Saturday she has been very unsettled, horrid watery smelly explosive poos, lots of wind and obviously painful farts, fussy when feeding, thrashing around and hating to be put down and not comfortable on my chest either, crying and pulling legs up in her sleep, developed horrible nappy rash last night and generally really distressed crying. Weight gain is still good, she's alert and temperature etc. all normal.
Spoke to HV at clinic this morning who has suggested a link to the introduction of the above dairy and has suggested cutting them out. Discussed going totally dairy free but she said to do dairy light first as there was no problems for the first 3 weeks when I was eating spread, a very occasional yogurt and 'hidden' dairy (cake, biscuit, chocolate etc.).
Has anyone else done this reduced dairy approach or have any opinions, experiences?
I realise that she is still very little so any change could just be the next phase but she was so pitiful and upset so soon after this one change that I can't just ignore it 
Thanks for any help, not ignoring you if I don't reply - just dealing with DD
