My friend had one for her when she had her kid in HK, think her mom wanted her to get one, they didnt have a helper.
We got a DH instead and the mother in law, DH helped with the daily household stuff, MIL made the soups, not that my mrs wanted to drink it but was told to LOL. I did all baby bathing as they were all too scared to handle such a little thing LOL. I had done my research on Youtube and it was fine, enjoyed bathing, changing the diapers, feeding the baby formula and burping her, rocking her to sleep on my belly, it was all fun fun fun, especially missing the poo missile that was squirted out when i lifted her legs to change her diapers. good memories.
Get a DH instead to help with the household so that you can focus purely on your kid and rest, let the DH take over some of the baby stuff while u rest and not just dump the baby on to the DH over night, your husband needs to step up and help.
