DS turned 1 a few days ago. With covid etc we haven't been able to take him to be weighed obviously and a house move in Feb meant that we had to wait to be put on the system in our new area so he hasn't been formally weighed since the end of January.
He was born very small (4lb 14oz) and has stayed roughly between the 10th and 20th lines as he's got older. At 8 1/2 months he started crawling and dropped to the 15th line but this was not unexpected! He then gained a bit back to the 20th line by 10months. However since 10 months he has not gained (or lost) any weight at all!
I'm not sure what to do. He is perfectly happy and healthy he hits all of his milestones etc. Do we just start encouraging more food?
