Hi Carly,
Have you found anything else about ur baby? My little maltese is only a little over 2 lbs, she is 5 months and intially she was pretty lathargic. She also seemed out of it. The vet also told me that she was a little slow. I had to force feed her for a bit there tons of Nutrical. Now she seems very alert, but she bumps into everything....
Does your baby bump into things?
