I chose helper over infant care as me and husband couldnt pick up my LO from the centre before 7pm.
Also helper there will be someone doing your house work for you (especially during your off days, you can take the baby and helper do the major works)
Of course its your luck if you get a good helper anot.
Cost wise probably around the same range depending if you have subsidy for infant care anot. But infant care it is not 1-1 service as they have 1 person taking care of a few infant & if your baby is colic like mine need addition attention.. most of the time I guess they have to just leave the baby crying just like in hospital as they cant handle more than one crying baby at one time.
&& infant care if baby is sick you have to take them home almost immediately so will this affect your work schedule?
You can always install cctv at home to monitor your helper while you are at work also. Just tell them is for security purpose.
If you can get your mother/ mil to dropby your place during your helper first few month i guess she will know someone is watching and buck up

End of the day be firm but nice to them im sure they are usually fine.
Lastly helper can give you good night sleep which you n your husband need to prepare you for next work day.. infant care at night u have to tc yourself & is super challenging! Especially first 3 mths
Hope you find what is best for your family!
