Secondly, they aren't white.. While some double merle dogs are almost pure white, they can go the complete range all the way up to a dog that you would think is a just a normal merle (most fall somewhere in the middle).
In between five and six months, your baby usually starts to sit up with your help, holding his head in an upright position, keeping the back straight. He may even be able to sit for a second or so without taking any assistance from you, before toppling down after a while [1] .
Most babies begin learning to sit up at some time between four months and seven months. Your little one could be sitting well without support by the time sheâs nine months old. Sitting takes your baby a step closer on the road to walking. Sitting usually comes after your baby gets the hang of rolling over and before she learns to crawl. Don't worry if your baby does things in a different order. All babies develop at their own rate and in different ways. To be able to sit by herself, your baby needs to develop strong head and neck muscles.
