Handicap, full time jobs and one more kid?

I'll try and make it short but explain as good as I can.

Me and my husband have a 1½ year old daughter and I've been thinking about getting her a baby brother or sister 😬

But we both work full time and my husband has a handicap which makes it hard for him to do a lot with her and around the house. And since I'm still doing an awful full time job, I need more hours in a day to make things go around 😅

He is handicapped in that way that he is in a lot of pain. He can't lift a lot, walk that much or stand for too long. Im not sure if anyone who hasn't tried it has any idea how that limits a life. But it's limiting shopping, house care, cleaning and going to the playground. Everything!

I was just wondering if anyone else have been in any similar situation and if you might have any tips and tricks and ideas?

Right now the plan is to wait ttc until she gets better at doing things on her own. But I'm not even sure when I can expect her to be able to put on shoes and a jacket and crawl into a car seat on her own 😅
