I have posted the ear flap hat previously. It can be made for a preemie, newborn, and 3 months.
The mittens in my photos are for an infant, but I also have a pattern for a larger baby I use often.
The sweater is called Lil Darlin' baby Sweater by Dot Matthews. Is it sized 3-6 months, but if you use a smaller crochet hook and baby weight yarn, it can made smaller.
