Our youngest Daughter had a tendency to give birth prematurely with her three daughters, DGD1 was born at 35 weeks weighing 4lb 10oz, DGD2 was born at 34weeks weighing 5lb 1oz, and DGD3 Arrived at 32weeks weighing 4lb 5 oz, they all spent time in the Special care baby unit receiving support and ventilation for a few days after they were born, before being upgraded to a normal cot for a few days prior to being discharged.
The eldest one will be 14 this year, she loves Sport and Swimming, her sister is 11, a right Chunky Monkey and a bit of a 'Couch potato' given half a chance, but she loves to cook and bake, and looking at her you would never believe that she was born so early. The youngest Sister is now 8, and the only one who was prescribed special formulae milk for premature babies, being the smallest of the three, and following the recommended guidelines at the time, she grew rapidly and is dreaming of starting Horse riding lessons as soon as the Covid restrictions are lifted. I'm sure that given time, your new arrival will soon be able to graduate from the Special care baby unit and start to grow into normal family life. Good Luck, I know it's rather stressful and worrying for you all at the moment, but I'm sure he will be fine.
