My 7 week old DD has not pooped for 8 days. It is clearly causing her distress as she spends al day squirming and straining, before the last full nappy she went 5 days and then 7 days before that, I am breast feeding only and have been told it is normal but she seems so distressed that i wondered if anyone had any tips to help her/me (the crying is getting pretty bad). Thank you
