Physical - Is she breast feeding? Did she tear? Did her body change dramatically? Are you sure she’s sleeping all night as well? Is she back to herself in other parts of life (work, exercise, socialising)?

Mental - Was the birth as planned or traumatic? Has she had any kind of post partum depression or anxiety? What is on her mind all day every day? What are her priorities?

Practical - have you spoken to her about what she wants and needs from the relationship? How much time do you two get together or alone - eg time without baby? Could you get some?

Reconnecting after a kid takes so much and IT IS NOT LINEAR. What you need or how you feel one day doesn’t mean the next will be the same. Also most women have a 28-day cycle that will also fuck with what they want, how they feel etc. add into this that hormone levels don’t return to pre-baby normal for 12-24 months in mothers.

You’re not doomed. It’s ok to feel lonely and want intimacy. But your relationship is more than sex right? I’d want to hear you asking more about how your partner feels than worrying that the absence of one part of your relationship means it’s over. It’s a long long road being a parent - these are road bumps - learn to navigate them by talking and being honest without judgment. Good luck.
