My 3 week old has trouble regularly pooping

[bills98]

I'm a new mum and have been told different things by different midwives/ health visitors.
My daughter tends to have a dirty nappy (poo) every other day. She has regular wet nappies.

I have been told that she should be going twice a day for a formula fed baby. Others tell me she that her going once every other day isn't uncommon.

Was told to keep up with the ready made milk once a day but I can't do that forever. When she goes it is the right consistency so I don't believe she is constipated.

Is it right that prep machines aren't hot enough and this could be causing the issue? Or is she still learning how to pass poo? (We've tried regular warm baths/ bicycle legs and belly massages)

Any advice on how I can help her? Could it be the milk she is on or the prep machine?

Thanks in advance. :)

Is she struggling to poo or is it just the frequency that is bothering you?
Is she gaining weight ok?

Just the amount she is going as I keep being told different things. The consistency of it is normal she just doesn't go daily. She is gaining weight correctly and still taking bottles with no trouble

If she's happy and healthy I wouldn't worry about the frequency. Every other day is fine if she's growing and not constipated.

Thank you for the advice :)
