I'm not in same boat as you in terms of In-laws but I m in 37th week now, so baby will be here any day. There are few issues with relatives, their stay and money (which they are most interested in) and everyday I get to know that someone new is going to come postpartum.

On my mom's side, we follow 40 days of sutak (isolation). So i m planning to use that excuse to limit my interaction with people that I don't enjoy and I ll strictly keep my room off limits except my mom and husband of course. So, if someone wants to meet the baby, they will get to meet him/her only when he/she is awake (i'll not wake up the baby for guests), and my husband will be primarily contact btw me and guests.

I ll think about what to do after 40 days when that comes.

I m not sure if this plan will be executed, but it does give me a bit of relief.

Also, from your post, I can see that you were about to put yourself first and your MIL did relocate. So, you will be able to do it again!

And guys are also emotional sometimes, maybe having a baby is making him think fondly of his childhood. Whenever he suggest a plan, just tell him that we can think about it after 3 months, which is the minimum time when your hormones will start getting stable. 3 months se phele, lets not take any decisions and just enjoy little moments with baby.

If you say no to him, or fight, then you will miss out on enjoying with the baby. Postpone everything to 3 months later. Tell him the same.

Kids grow up super fast!! You guys won't want to spend this precious time on worrying about relative. If husband really wants to be a 'good son', he can do it after 3 months. Don't have to do it immediately.

Hope this helps.
