I have 2-month old and before he was born lot of people said to me that "dads can't do much in the first 6 months". I was like ok, we'll see how it goes.

After he was born, I quickly realize dads can absolutely do everything except feed the baby directly from the breast. Breastfeeding itself, depends on the baby and mom, is fairly quick, maybe like takes 15mins every few hours. That leaves about ~22 hours each dad can be part of the activities, like changing diapers, bathing, soothing, having the baby sleep on you, putting the baby to sleep, reading, changing clothes, singing etc.

This "dads can't do much", "there is just this bond with the mom" and "it's biology" seems like bullshit or an easy out from taking responsibility. The bond happens if you just spend time with the baby.
