There are a few issues here. Leaving the family issue aside during CNY, most important is that u need to talk to your HB regarding taking your Baby Back during the night time.

A Baby Sitter (BS) is just a Baby Sitter. Parents should take care of the Baby whenever they can. I hope that u are already taking care of the Baby on weekends. Else, the Baby won't even know that you're the parents.

Look for a BS nearer to your house. Talk to your neighbours, who ia willing to help you.

Above all, talk to your HB that being away from your Baby is killing you emotionally.

Good luck. If you need someone to talk to, Call Befrienders.
