Aw mama, yan talaga ang struggle when we go back to work, nakikita natin ang pagbabago ng appetite at sleep schedule nila. Definitely bring this up sa pediatrician mo kasi ang underweight combined with the picky eating at limited nursing time ay kailangan talaga ng professional check-up; baka may deficiency or need sya ng additional nutrition na kailangan i-assess ng doctor. In the meantime, a few of us mums tried adding more calories to the food he will eat, like mixing a bit of butter, egg yolk, or even coconut milk sa kanin niya, or offering peanut butter on toast para ma-increase ang calorie intake kahit minimal ang variety. The 7pm to 6am nursing window is quite limited din for his age, so when you're home, try to maximize those feeding times and maybe add formula or nutritious snacks during the day with his yaya, pati banana with peanut butter, cheese, or soft scrambled eggs. Kaya natin ito, pero talaga kailangan ng doctor's guidance para sigurado.
