樓主, how old is your baby? (我無惡意). Do you need cook congee on Sat / Sun or still at milk feeding stage? Cos you would be getting more and more busy when your baby is growing up. You'd better have more 心理準備.
I am also a working mama and take care of bb after work on Mon-Fri and full day on Sat and Sun. I feel very tired also in particular on holiday. But seems I have already got used to this busy life after several months and enjoy every moment with my baby! You would get used to "being tired" very soon ^^. And I will 呻 in front of my parents and husband (有時呻下心理上舒服d), but not 6299. My 99 is an easy-going person and ok good to me but I still won't 呻 in front of her. Cos you dun know what she will think in her deep heart.
Cheer up 樓主. Your lovely baby is your biggest support.
