Not sure about the jammies but I know their regular cloths run very big. At 31 lbs J fit nicely into their 18 month cloths that claim a much lower weight range.
Joe is 17 months and I JUST packed up hi 12 month PJs from Children's Place. He wore them from about 11 months until now and they held up beautifully!! Very good quality PJs, so buy them large--they last a long time.
i've never tried their PJ's but as PP said, their clothes, ,IME, have run HUGE. I bought DS a tank top for summer vacation last year 6-9 months... it was pretty big but still ok- DS is now 22 months and it fits perfectly.. however, i have a small kid.
Re: Do the Children's Place PJs run big?
this is very true with these jammies. They look ridiculously long but once you wash them, they shorten up nicely.
