19 days old.. poop problems!

[TheHermitCrab]

My 19 day old baby pooped ( a lot!!) 2 nights ago.. and nothing since!!

I have stopped combination feeding in the last few days and is now 100% formula (was getting about an ounce of milk in half an hours pumping!) and I have just started her on infacol.

Could these things be affecting it and I've just gotta wait it out?

She is making very stinky farts... but nothing to show for it at the moment... not sure when it stops being a waiting game and I need to tell a doc?

(I've tried warm bath and legs stretches)

Hi,
Congratulations on your baby, I have a 19 day old little girl, so snap on birth dates!
I'm sure I was told that they can go some days without a poo.
You could try gently massaging the tummy in a clockwise direction.
I'd be inclined to call and speak to the midwives or your health visitor, especially if farts are smelly. My girls facts don't smell at all, but she's breastfed so that probably effects it.
I'd get some guidance from a health care specialist.
