Like some of the girls said you adjust with your own and you & your OH should be a team. Working well in my house

I was exhausted when I had my lil sister (shes like 4 now) & when I had a friends lil one a few months back but they aren't yours I don't think that instinct is there - doesn't mean you take less care of em but it is defo different with your own.

Hope you got some kip - Remember pregnancy will shatter you even more at the moment.
