Just some opinions from some mommies!?

Just a quick question. I was taking my mother into work today at 645am. I left my 15 month olds Pajamas on. She told me that it was abuse to keep them on. I got REALLY frustrated and told her that hes my baby and if I want him to wear Pjs then he will. I also told her that shes the reason I got married and moved out. I dont know if I am overreacting to her comment. Me and my husband are 8 weeks pregnant due date 1-11-11 ( well Im pregnant but you know) Do you believe letting a 15 month old wear his pjs for part of the day is abuse? Do any of you ever let your baby/toddler out of the house in onesie PJ's?
