same situation mamsh, single mom here and he's 4yrs old.. pero maintindihin sya, lagi ko sinasabi sa kanya na i'll go to work again tomorrow, kasama nya again si papa(lolo) and mamu, and i'll come back again after work.. I started working again when he's 3yrs old, pero ako nag alaga sa kanya from birth to 3yrs old.. we still have our bonding time pag umuuwi ako sa hapon and during rest days.. so, di sya lumalayo sakin.. nakakatunaw pa nga minsan na sunasabi nya sakin, "i miss you mama", "i pick flowers for you mama", "i wuv you mama", "mama let's play".. make up for your time lagi para may interaction pa rin kayo π
