Yes, normal feeling lang po ☺️ It's the same for me, 3y3m si firstborn nung lumabas si bunso. Nakakalungkot dahil extended breastfeeding pa kami noon ni firstborn, pero nagwean kami dahil nagkaroon ako ng nursing aversion during my pregnancy. Extra challenging during the 4th trimester dahil adjustment period naming lahat (ako, kuya and bunso). Pero after that, I'd say it'll get better.
Basta kausapin nyo lang lagi nang mabuti si firstborn, nakakaintindi na naman. Si kuya ngayon, albeit medyo hindi nya pa lagi managed ang emotions nya, ay very loving and caring to his now 7month old baby sister ☺️
