7 months and you should be crawling now. But you seem to be in no hurry. Rolling on your stomach seems to be a very convenient option for you for now. One major milestone is you are able to sit on your own without any support.
We have shifted to our own little flat now. Papa has seen that you have every little comfort that we can afford. He has fallen head over heals in love with you. The most tender moments are when you are fast asleep and papa sits beside you just staring at your face for minutes together. You should see his face flushing with emotion and all the love he can manage to pour.
