In the first 5 weeks.
DS was born 7lb13 so quite an average weight, he lost 5% and was back to birth weight by the time he was about 8 days old. At his weigh-in last week (when he was 5 weeks old) he weighed 11lb1.
This seems like a huge gain to me - is it normal? My last baby was born quite small and while she gained weight fine, it was nowhere near this fast.
His 0-3 clothes are already getting too tight but it seems ridiculous he could be in 3-6 at 2 months old.
Looking for some reassurance I suppose!
