Have been a bit concerned as he hasnt been regular with his poo's - like only poo'ing every 3rd day but boy he has made up for it today!!
Are you breastfeeding? I had this concern too (but with Veygas having this hernia, I was told to watch his bowel motions!) But I discussed it with the ECH nurse this morning and she said it's normal for breastfed babies to go up to two weeks without doing a poo! But she also said with a hernia, to be concerned if he doesn't have a dirty nappy after about 3 or 4 days (he hadn't had one in two days, which is why I was worried)

But I agree, they certainly make up for it!

ETA: Duh, you were talking about expressing before, so I gather you are breastfeeding!
