working WITH My 7month old

Working with my seven month old!
Working with baby! 
So i  have nobody to look after my little one , plus i am still breastfeeding
So going back to work is not exactly what i am into
But we started going for visits together with the baby to our retail shop
Sometimes i even spend three or four hrs
Because i feel i NEEd to work! So i get back into busines and then i feel guilty for not spending quality time with my baby
Is it ok to make him spend time in the shop? I feel like i am doing something bad or wrong. But i cannothelp it and also my husband needs help with the business
