With all the winter gear talk, I'm finding stuff on clearance at Target (mainly a snow bib) for DD who is 8.5 mo now. But even at less than $10, I worry it'll go to waste if she isn't 12m by the time she is 12m, although she is pretty avg and true to size now. Then I'm worried that 18m is too big and won't work if she's swimming in it either!
