I sort of agree. For me the first 6 months was learning to be a mother, learning a new rhythm after years of working, making friends and connections - some that stayed with me for years, having new mums over etc etc etc. I didnneed a husband in the mix. We both found that first year quite stressful. The house was tiny so there was no getting away from each other to reset etc.
When my husband started working full time from home about 5 years later, we had another period of adjustment while we both got used to it and the difference of him being home all day every day.
To have done both together wouldn't have worked for us.
However, better family benefits when the kids were a bit older would be welcomed - so its easier for him to be able to take time to go into school/nursery for the nativity, parents sessions, to see a sports match or a choir event....without having to use days leave and then leave us short in the school holidays.
My husband isn't useless. But I didn't need him those first 6 months. Baby 2 and 3 slotted into our life and rhythm. Having him home then would have disrupted all our routines. Any child of mine that found pre-school a bit tough would find going even tougher if Daddy was at home.
6 months paternity to follow mums maternity - yes yes yes.
