Hi,

i used the love me baby wrap which lets the baby have arms up but wrapped so that bub can mouth its hand it wanted. It also has a double zip for nappy changing, the are about 40 each sizes S, M or L i think i used S and M and then i bought the 50/50 which is the transition wrap that has zipable arms you can take one off at a time to get bub used to having free arms so you can transfer into a grobag...

highly recommend!!
