I am 70 in a couple of months & although I adore the 2yr old & 8 month old, they are tiring & heavy to pick up from the ground. (bend the knees, I know!) I do one full day 10-7 with both, then fill in sometimes 2 more days with one child. My partner who has never had kids find it all a bit much so my loyalties are divided & i find I am having to be fair to both partner & grandchildren. My daughter works full time as a journalist & helps on their farm, so has absolutely no time to herself & hardly to speak to me for more than a moment. I know things will improve. The baby is crawling fast & toddler very active, so it is rather full on. I am not complaining - just wonder how other gransnetters cope?!
