I currently breast feed my 7 week old baby, he isnt the best sleeper so we've been giving him aptamol milk before bedtime to try and fill him up so he'll sleep a little longer letting us get some much needed sleep, as he can be up a few times overnight for a breast feed. The aptamol hasnt been making much difference so i am considering using the aptomal formula before bedtime? As people say its heavier so aids sleeping a little. Has anyone else done similar? What is the difference between aptamol milk and the power formula?
