We made a play pen for our baby, but he became very depressed, he's 7 months old now and we can leave him in the house with no problem. We did get a patio panel that has the doggie door in it so he can go in and out with no problem and it's been great. We have a neighbour that's home all day so she tends to keep an eye out for him, she loves him too. You may have to crate your baby for a while but keep your fingers crossed, you never know, he may be good out on his own. appicon
Good luck,
