Skipping appointment

Hi there, i just get to know im pregnant with #2. #1 is just 11 months old. I do not have any helpers, in-laws, parents or any other kind of other help. Its just me living with my husband and kid. Question: 1) How do mummies manage to attend appointment along with #1 while having #2 in the tummy if husband is working? I applaud you for being a super woman. 2) In this situation, is it wise to skip appointment? Or which are the important appointments that i should attend? 3) Where should i ask for help? Thank you.
