I'm taking my baby away on a long weekend trip (3 days). I'm bringing his lights and food of course but not sure of the size and type of temperary viv to put him in. I need something mobil of course so his 40 gal won't due. He's 4 months old and about 13 inches long if that helps. I can't get anyone to watch him so he's going with me, that and I can't stay away from my precious baby for more than an 8 hour work day . Any suggestions or advice would be GREATLY appreciated. Thank you
