My 3 month old still has very minimal head control, tummy time she holds it for about 5 secs then puts it down and just lies there. When you pull her arms to do a 'sit up' she doesn't hold it at all. My older two seemed much stronger at this point so don't know if she is behind, a bit lazier or if the other two developed it earlier? Can anyone tell me when their dc managed a bit of head control, anyone's particularly late but was developmentally fine?
