My babies have been dressed since the day they came home from hospital. Don't get me wrong they're not wearing tweed and leather and stiff scratchy denim but they do wear lovely little outfits and I love it.
I personally think "sleep suits" are for sleeping in, and for my friends that say they are "baby grows" and babies wear them while they're growing, well, babies do most of their growing at night so my arguement still stands.
My first pregnancy was just the most miserable of experiences and the only thing that really cheered me up was filling online shopping baskets of either little boys or girls clothes ready for when they popped out and I knew which basket to buy! I was excited to have my very own real life dress up dolls and I still am. I enjoy shopping for my children more than I enjoy shopping for myself and whilst I leave the house looking dishevelled and a little bit dirty my kids look great. It seems pointless, it is I'm sure, but I like seeing them looking nice.
I find dressing the babies serves a purpose as well (other than them looking fabulous). I am not really one for routines. I don't impose strict 11am nap times and lunch time is when ever people are hungry but I do find that getting dressed in the morning and getting ready for bed in the evening helps both me and them mentally prepare for what's to come, whether it's starting our day or going to bed.
Perhaps more importantly it helps me feel like I have achieved something with my day. If me and the kids are all up and clean and dressed I feel like we're ready and raring to do something with our day, even if we don't end up doing anything. I feel more motivated to leave the house, or tackle a "day out" and then the days when we don't go out and we don't get dressed are a rarity and a treat. We LOVE pyjama days! My toddler is positively excited by them. We sloth out in pjs and watch
