yes definitely. Its a fitted nappy which means it has no waterproof layer to stop wet getting through to the clothes. I would suggest using a ME Airflow or Rikki as they are virtually bombproof, and work especially well with MEOS. How much does your lo weigh? I have a few very worn, but still very serviceable airflow and rikki medium wraps, that I could send to you to try. They're medium so will fit approx 10-20lbs.
I personally didn't get on well with MEOS as the crotch was too wide for Max. I found sandies slightly better but I now use a mixture of pockets, all-in-ones and other fitteds. Its just a case of finding what works for your LO - am still making (somethimes expensive mistakes) with Max
I would recommend browsing the Reviews section. For fitted go to viewforum.php?f=25
and for pockets and AIOs go to viewforum.php?f=26
If you have any issues with the different types of nappy or abbreviations then the threads on this are very useful: viewforum.php?f=21
Other than that ask lots of questions as its a very friendly community. Hope this all helps
