So do I!!! Cooper is 5 months old and already weighs about 4.75 pounds!! He looks like a giant compared to Atticus. We have had to teach Cooper to not be rough with Atticus since he is so much smaller. Cooper will get a little rough and now all I have to say is Cooper be nice and he will stop playing so rough! But the adjustment is going way better than planned!
It is hard to believe we have already had Atticus for a week already! But I am sure your girls will get on just fine
