Thanks for replying ladies.
We have tried the following:
Warm baths daily
Cycling her legs for up to 10 mins about 3 times a day
Massaging her tummy - seems to help but not with passing but age will squeeze when massaging
Have given gripe water - not as per dosage - but dipping dummy in few times over the day

Last MCHN check up DD has gained 140grams, that was a week ago
Last poo was on Sat night, DH said it was dark yellow and runny, but small amount.
Last formula was 60ml yesterday afternoon (previous few days has been similar amount 1-2 times in the day)
Her feeds have been regular 3 hourly but she can take up to 1-2 hours to feed and she's not full, hence the top ups, BM when I can get time or feel there's still some in there (not all feeds require top ups)

Originally the midwife who saw us at home suggested the top ups due to my milk not coming in fully (post traumatic birth issue)

Well went to pharmacy today and advised to use Lac-tol and if DD still no poo's by Friday to take her to Dr.

SIL said to try massaging olive oil around anus - so will try that tomorrow too.
