Have been weaning DD since 6 mo (now 7.5 mo). She's not eating a great deal - not a fan of the spoon (except ready brek and greek yoghurt) so persisting with finger food which she will have a play with and a bit of a nibble. In the last 3 weeks after a few minutes she makes this frustrated straining noise while eating - like she needs to poo...but never results in anything...can go on for 10 minutes or more. Shes stared doing it with her milk now too today. Sometimes she continues to eat, other times refuses more food. What on earth is it? She looks really uncomfortable and her little face goes red, but never seems to result in wind or poo. Any ideas?
