Para po sa akin, in terms of baby's connections to their caregivers ay mas attached at naiintindihan na nila kapag ganyang 2yo or toddler age na sila. Mas attached na sila, unlike nung 1yo or below sila na parang wala pa silang pakialam. I think normal lang na sobrang malulungkot sila pag nagkahiwalay kayo but I don't necessarily think it affect their development. I think that will depend on what kind of nurturing yung makukuha nya from your parents. If maganda rin naman pagpapalaki sa kanya, then there shouldn't be a problem. You'll just have to give more effort to keep your emotional connection and good relationship with your lo.
Unsolicited comments ko lang po about your plans: make sure po that it's actually worth it, financial-wise. Kasi nabanggit nyo rin po na uuwi kayo sa Bukidnon quarterly, baka yung matitipid nyo sa rent, mapunta lang sa airfare. Then tiyak magpapadala rin kayo ng pera back to Bukidnon while your lo is there. And same with the income, make sure that the business your planning is stable enough to give you the same if not more income compared to when you're employed. Otherwise, sayang lang din naman ang mga sacrifices... Good luck and God bless po...
