The fact that a factor in baby care taking (breastfeeding) is only possible for females creates a small bias in favor of female care taking.
The factor is small, and can be mitigated with little (but not null) effort.
My point is that OPs argument holds some water. Notably, it suffices to support the statement 'women are more likely to want to be care-taker than men'. There remains an argument about magnitude, and compensating effects, but there is a difference.
