Matthew was somewhere in the middle, development wise he seemed to be doing things at his actual age, such as smilling etc, think he doesnt go for toys/objects yet as his hands are still quite small. As for sleeping thru night it just kind of happended, he would go to 4.30am before looking for a feed, then say 6am now he will go from say 9pm to 8.30am I checked with HV as he was only taking 4 feeds which I thought was not enough for his size but she said he'd soon tell me if hungry - he was sleeping through from about 3 and a half actual age which was roughly 8 weeks corrected, which they say is the norm.
Matthew can be weaned anytime now but im gonna wait til hes 6 months as so far hes showing no signs of interest, if we give him the odd thing to taste he'll take it but were not in any rush - yesterday he opened his mouth at the sight of my finger with teething gel rather than waiting to feel it on his lip which is an indicator of readiness as well I think.
Your baby will come on so so much the next few months, with Matthew it is just his size that needs to catch up, people comment that my 'newborn' is so bright, alert and into everyrhing haha and hes 5 months next Thur x
